I used to shoot at the Angeles Range off the 210. They only allowed one shot per 5 seconds (“no rapid fire blah blah”) but the range safety would always joke and say “but you black powder folks can shoot as fast as you want.” So I loaded up ten rounds of black powder .303 and mag-dumped that thing in like 2.2 seconds.

It IS 303 British to differentiate it from 303 Savage which is the reason they started putting 303 British on the box.

[@robertstump4740]

Of all the BP cartridges, the 303 British is probably the most complex. Without access to a special puck mold and straight walled 303 cases, you are stuck with what you had to do but you got close. That central hole is critical to increase the burn rate of that molded charge in order to get to 1850 fps. You could try other powders (many suggested your TP version) but my hunch is you are near a velocity wall without that central chamber. The fact the armorers had to go the route of a specially molded charge indicates to me they failed with stuffing the case with loose powder. ....and they had some damn good powders in the late 1800s.

[@irregularguy6465]

what if you made a puck mold to form "segments" of the full powder grain, just small enough to fit through a full .303 case neck?

[@robertstump4740]

@@irregularguy6465 Hmm, kinda like orange slices and slide them in from the top? It would be tricky as that last piece would be almost impossible to insert. I had some success(?) with my 40-50 making a central pin indexing on the flash hole, pouring in powder around the pin and compressing with a ram center drilled to allow the pin to slide through. It took 12 min to make each cartridge and no real gain in MV so I gave up.

[@irregularguy6465]

true, and the orange slices method would require the segments to fit into the central chamber too. Maybe some kind of an expander mandrel that compresses the powder against the inner walls of the case? or an even bigger expander mandrel to un-neck necked casings?

[@robertstump4740]

@@irregularguy6465 I think the latter idea would have the best chance: anneal the cases, expand the neck enough to insert the pre-formed molded charge and then resize the case around the charge.

If you want to continue your experiment, you might want to try staying with the 4F and try both a drop tube and separately, vibration to settle the powder in the case prior to your "compression die." I've done so in 45-70 to good effect, and you might find you only have to compress once prior to the final insertion of the bullet.

I completely disassembled, cleaned, and inspected the rifle. I took the barrel/receiver assembly to a gunsmith and had a new barrel fitted to the receiver.

The pressing technique you use is really similar to the method of making blasting caps using perchlorate based explosives.

Triple seven does not like compression - Hodgdon recommends that it not be used with compressed loads.

Triple seven does not burn well or burn predictably when compressed. Compressed loads did not produce increased velocity even once out of 12 shots. There were no signs of detonation when I tried these loads, but you are on your own if you try it as compressed T7 loads are against the manufacturer's recommendations.

You might actually get better velocities with a heavier bullet. I've heard of that happening in black powder cartridge loads due to light bullets being pushing out the muzzle before the pressure curve can properly build up. Either way getting ballistics on par with a .44 Mag carbine isn't bad at all out of a black powder loading.

I use an RCBS decapper body as a kind of universal dye for flaring and expanding. I bet you could make a compression mandrel with a long pin that would compress your charge and leave you with a hole down the center, and would be a lot more convenient than seating and pulling a bullet multiple times. You got higher velocity with a faster / smaller kernel, so maybe you need to burn the charge faster by exposing more of the powder column to flame?

Not an expert here, I think I read back in the day hand loaders would use duplex loads of 2Fg and 3Fg powders. I forget the ratio, something like 20% 2Fg and 80% 3Fg. Drop 2Fg and tamp it with wooden dowel then the 3Fg and tamp that as well with a wooden dowel. The point is at that time they were using compressed loads and to compress the powder they used wooden dowels and a brass hammer then seated the bullet. It was dangerous from what I remember reading. Static electricity.

Fascinating experiment. I spent a career in the US Army Infantry, mainly shooting 5.56mm. I could not image being on the battlefield with a rifle chambering something as large as .303 British.

[@robertsmith4681]

Statistically it was kind of the other way around, hit probability was just as low as it is today and with fewer projectiles coming out of a bolt action with a 10 round magazine compared to an automatic with a standard 30 rounder one would expect fewer hits, also the training was different and men were sort of less likely than they are today to pull trigger "with intent". Modern training methods and so on.

Since I have exactly zero experience handloading black powder cartridges, I might be wrong, but would you benefit from dividing your powder charge in half, compressing the first half then add the second half and compressing that, I understand that a purpose built tool would be needed, I’m thinking a brass punch that’s modified to thread into an old die that’s been tapped and rigging up some mechanism so you compress to a consistent pressure, perhaps another tool or fitting that would allow you to remove your press handle and use a torque wrench in its place. When I saw your process that was something that came to my mind. Then you would have a consistently compressed load compressed to a consistent “weight” or pressure for lack of a better term.

[@vicroc4]

That would be my guess. I know in a smokeless load that 5.5 inches could cut off ~100 fps or more depending on the specific load. In fact, that was one half of the impetus for the development of the .300 Blackout cartridge - neither M193 ball or SS109/M855 penetrator were designed for the 14.5 inch barrel found on the M4 carbine, and thus deliver less-than-spectacular terminal performance when shot out of the short barrel. A big heavy .308 caliber bullet can do more damage even if it's moving much slower, or so the thinking went. (of course, the other half of the impetus was for a subsonic round that carried more energy than a 9mm and could be easily used in existing platforms with minimal modification)

Could the stated muzzle velocity of 1850fps be due to the use of the black powder .303 round being introduced whilst the Lee Mitford and or Lond Lee variants were still in service?

I’m not certain on the exact dates but at some point, around the turn of the century the MkII and soon after MkIII smokeless cartridges were introduced whilst the SMLE (as per your demonstration rifle) was introduced in about 1907 with the shorter 24.5 inch barrel. Suspect that the 5.5inch shorter barrel could have something to do with the missing 100 fps. I’m a member of the Lee Enfield Rifle Association (LERA) in the UK and ill ask some of the guys who have older Long Lee’s (and Martini Henri .303 conversions that used the same black powder cartridge) what the service and introduction dates for the rifles and the cartridges are.

If you need to increase packing density, try mixing small and large grains. at around 29% of main diameter you can fit smaller grains between the gaps of large ones without increasing volume. This is widely used for concrete where different sizes of gravel and sand fill most of the space with the cement merely acting as glue.

You would think it would increase MV, however I did some testing and got just the opposite. Same powder/load going from LR to LRM I lost 60 fps and more than doubled the ES. The velocities were very erratic. Some postulate the stronger primers actually push the load forward before ignition can occur. If this is true then the bp starts burning in an enlarged volume so you would get less pressure. Many folks in the BPC community actually drop back to a LP primer. More testing needed.

@@concernedaussie1330 it will definitely increase the velocity but I doubt it would make 100fps worth of difference

[@concernedaussie1330]

@@Everythingblackpowder 👍🏻 just saying. My brother played around a lot with diy BP in rocket motors . There’s a lot of tuning & different power levels involved with shapes & surface area . We’ve discussed the 303 pellet topic & his opinion was the British were on top of their game back then & without forming the cartridge around the pellet it would be very hard to equal or exceed their performance!

[@wolfpack1384]

Hey I was wondering im sure you heard of chimney fires? I was wondering if when someone cleans there wood stove why not use the creosote as charcoal for black powder. Clearly it's flammable

[@Everythingblackpowder]

Yes it’s powerful but the fouling is absolutely awful

[@wolfpack1384]

@@Everythingblackpowder ah OK thanks was thinking of homesteading and being self sufficient. Nice to know there's someone who's tride it so I don't have to lol

[@MattGoodman-vl7th]

Last I checked Buffalo Arms sold a die for 45-70 that would compress the powder evenly and create a central hole for "even ignition" or something like that. I've got one but haven't had time to play with it. I do plan to see if I can adapt it to other cartridges like the 303 British.

[@MattGoodman-vl7th]

Loved the video by the way. Love all your videos. Experimentation is the most fun part of loading. Thanks!

[@nonokodog622]

Not an expert...but I really think the larger grains are used when the bullet is large, like over 300 grains. The power over the complete burn time is the same. But the power vs time curve should peak sooner for FFFFg. That's b/c the small bullet doesn't need the slower burn rate to get the bullet moving. A big ass bullet, would need a slower burn rate to get the mass moving. I'm left wondering if bullet without a jacket would perform better with the 4F ? I think that jacket causes more friction and pressure so the 1F was happier if less velocity. Someday soon I'll make my own damn video when I get my new shop setup. Great video !

It’s more like a guide line than a rule.

When did black powder measures move from volume to weight?

[@cameronlamb7274]

The .303 name thing is common enough even up here in Canada theirs plenty of .303 savage rifles kicking around so .303 British it is.

[@cameronlamb7274]

As a side note PPU brass is as close to military brass as it gets.

[@r.fusterman1660]

Disregard those nomenclature police who lack historical perpective. As already commented upon, the terminology was necessary back when .303 Savage was a thing. They might as well ask "Why do you call it .308 Winchester? Well, .308 Norma, for one. Nowadays we have the same thing with .338, 6.5, yadda yadda. So let 'em eat fish. "And as always", pretty dang informative and entertaining presentation.

[@cziprick]

Not sure if this was mentioned (I didn't watch the whole video 😔) but Black Powder was only used in the .303 from 1888 to 1890. From 1891 to (I believe) 1917, an early form of Smokeless Power (Cordite) was used. Cordite was the original intended propellant in 1888 however BP was used for a couple of years til the Cordite was developed. I believe in Canada, more big game has been taken with the .303 than any other round. In Some treaties with First Nations Peoples in Canada, A box of .303 ammo is provided to families as part of the treaties to this day.

[@Mbartel500]

I guess I don't see the point of using black powder in this cartridge. It's messy, the rifle needs to be thoroughly cleaned after each session, velocity is much lower than using smokeless, and the reloading process you are using is more tedious and time consuming. Did you do this project because there is some benefit of using black powder instead of smokeless? Would you mind sharing what those benefits are? Or was this merely a curiosity endeavor?

[@Everythingblackpowder]

Lol, there are clearly no benefits when comparing this to smokeless powder. My goal was to try and match the velocity and power of the original black powder 303 cartridge, which it failed to do by 100fps. It’s purely academic.

[@Mbartel500]

@@Everythingblackpowder copy that. I think the formulation of black powder has changed a few times in the last several hundred years, so maybe the black powder in common use in the late 1800s and early 1900s burned a little hotter and/or generated a little bit more pressure. Or the barrels used back in the day were bored and rifled to a slightly different specification, when this cartridge was first developed. In any case, I enjoyed your presentation, and will look forward to more of your videos in the future. Thank You👍👍

[@FiddlingOnTheRoof]

Could it be that original BP .303 cases were "balloon head" cases like the original .44-40 cases? When I was shooting cowboy action, I could only get 30 grains of 3F into a case with 1/8" of compression using modern Starline cases. In a balloon head case, the bottom of the case was actually below the primer pocket. That would explain how modern cases won't take as much powder without going to such extremes of compression.

[@Everythingblackpowder]

Possibly

[@IamtheIZ0D]

As someone trying to coax some sort of accuracy out of a worn out 1917 SMLE, this is fascinating. I do wonder if Magnum primers would make any difference here. I know they do with my compressed 45-70 loads.

[@Everythingblackpowder]

I’m sure it would pick up some velocity

[@curteaton]

Thanks for not wanting to offend the Commonwealthers, but it's your video, so offend away if you want. While I grew up around .303 "British" the truth is i didn't even know it started out a BP round until the last video. Always more to learn.

[@johnfisk811]

Trivia but it started out as a smokeless round but the smokeless propellant had issues so it was issued as a temporary stop gap with black powder whilst the issues were solved. The solid cake stick put one prior to necking the case was the typical way it was done at that time and leaned heavily on the Swiss research and was similar to the Danish and Austrian practice to name but two. If one looks at the Swiss Schmidt Rubin rifle one can see that it was rear locking to keep black powder fouling away from the lugs to reduce fouling issues with the bolt. However they were able to get a smokeless round ready before it was issued. But then the Swiss had different environmental and transport situations compared to the British who had to be able to support travel across oceans and in ox carts across rough roads etc. in temperatures ranging from extreme desert heat to a Canadian winter and weeks of monsoon rain.

[@OhmSteader]

I was thinking of it like filling a post hole having to tamp it from the bottom up for best results. I cringe when packing powder so tight. Have you ever heard of a loader exploding? What is the loader you use?

[@Everythingblackpowder]

No, I’ve never heard of a case exploding on a loading press. The one in this video is a RCBS rocker

[@jofher007]

Hey Jake did you use this same procedures when you "assembled" the .308 win with FFG few months back

[@Everythingblackpowder]

No, I’ve never tried to compress powder in a cartridge like this before

[@dp-sr1fd]

There is also .303 Savage, I think this is different to 303 British. The profile of the case is not the same.

[@shug831]

I love the channel, your lucky being able to own guns. I'm a engineer and i was wondering if a tool couldn't be made to compress the powder into a tube say 0.300" and that could be dropped into the cartridge? I never knew you could compress powder into shapes. Or am I talking BS. 😉

[@wallyzworld7108]

Could you split the difference say 65 grains? Then using a long drop tube to get the powder charge right at the case mouth and compress once while seating the bullet for better consistency. I think a Sinclair case mouth expander die might work for compressing powder also, use a 308 expander mandrel to compress then powder and not effect the case neck on the 303. 303 British ammo is marked with British to differentiate it from 303 Savage that was also available here in the U.S.A.

[@Everythingblackpowder]

I highly doubt the use of a drop tube will allow for an extra 10gr but it’s worth a try

[@firestorm8471]

The black powder .303 Brit round had a compressed powder charge pellet placed in the case before bottle necking the case didn't it ?

[@Everythingblackpowder]

Yes

[@firestorm8471]

That would be nerve wracking ,,to say the least. Hell, my butt would be drawing up pretty tight even compressing the charge in the manner you did it.

[@Everythingblackpowder]

lol I like to live dangerously

[@murphy4yt]

Really enjoy your videos. I was just wondering, maybe a drop tube would relieve some of the tedium of compressing the load five times. Just a thought. Have you tried your toilet paper powder with this cartridge?

[@Everythingblackpowder]

Not yet

[@victortuten4399]

I have a weapon my grandfather carried in WWII, it takes 303 BRITISH! I also like to shoot 3f in my rifle. To each his own, you do you! I wonder how close this would be to the original with some toilet paper powder... I also wonder how a turned down dowel would work to compress the powder...

[@johnfisk811]

More trivia but the American 30-06 round in British service (RAF and Home Guard) was designated 0.300” and a red paint band put on the rifles and machine guns to prevent some dimwit trying to shove .303” down them. Post Great War the French used many German Maxim guns in 7.92mm Mauser but they changed the French standard round to 7.5mm and that could cause severe issues if they were mixed. They then changed the French round length so that it would not fit inside. Accurate names matter.

[@geoffkeahey2651]

Might try magnum primers. would probably light off that densely packed powder better.

[@tompuckett9937]

I’m thinking the old cases for the old Lee Medford rifles were probably balloon head cases, which would accommodate a bigger powder charge. I’m also wondering how they would accurately measure the velocity back in the late 1800’s???? Really fun and interesting video. One more thought, the original Lee Enfield had a barrel length slightly longer, maybe upto 3” longer. Can’t remember for sure. Still wondering how they would accurately got that velocity with the original 215 grain bullet??? I’m finally done thinking and wondering!!!!

[@Everythingblackpowder]

@@tompuckett9937 yes, the Lee metford did have a longer barrel.

i do wonder if the heavier bullet would actually "make more power" ie not loose that much velocity but gain in ft lb of energy and gain better down range performance from a better ballistics coefficient
