I'd bet a whole dollar that the chronograph is struggling because of the wads. The thing works by timing off of the shadow of the projectile, right? But when the wad flies through and leaves a significant enough second shadow, the chrono doesn't know what to do and cries for mommy. That's my theory at least. Great episode, and thank you for the content! Here's either a $5 tip, or $4 and settling a $1 lost bet.

I always enjoy the duplex videos. I have had good success with 45-70 smokeless kicker under BP for a good clean burn in my Sharps rifle. Recently, I experimented with a smokeless kicker under BP in 357 mag brass loaded as a blank to reduce fouling for my YT algarithim short vids and I noticed that while fouling was reduced flash was also reduced and the shots appeared similar to smokeless which doesn't charm the algarithim if you know what I mean.

[@FCFDave]

I don't have any BP rifles, but do a lot of .36, .44 and .45. I'm sure you've checked, but on my (cheap) Caldwell chrony I have to wipe down the windows with an alcohol wipe after every few shoots or it quits wanting to read. Hope it helps. And of course I love the videos.

[@musketbal]

Hey, I have a 1853 pattern Enfield that Hiram Berdan had converted to what was almost a exact copy of the action used on the Springfield breach loader muskets adopted by the U.S. military. On the flat of the opposite side of the stock is stamped, "Patented Feb. 27, 1866." It is in excellent condition. From what I understand Berdan had Remington/Colt do the breach conversion. He intended to convince the British Government to use his trapdoor design. However they went with the American inventor's system, that being the Snider version. I had the ejector repaired by Lodgewood Manufacturing. I am now making cartridges to shoot it. I did see someone else use a wooden plug used and inserted into the base of the bullet like the the original Enfield ammunition. When the case ignited the plug would be forced into the base of the bullet allowing it to expand the base of the bullet into the rifling. I was going to use a 3/8 plug cutting tool, however I found 3/8" oak flat head plugs with a slight taper. When pushed into the base of the bullet using some bullet lube they seem like they will work as intended. I have not fired the musket yet, however I think it will work fine. The plugs are made by Madison Hill, 3/8 (.953) . The order number is 9005-19003-9005M. They were purchased at Lowes .

@@musketbal excellent

[@gunrunner5095]

My favorite plinking load for the 45-70 is 15gr of Unique ( the old formula because I bought a ton when they cleared it out), a fiber wad and a 300gr Lee cast bullet. Never chronographed it but it shoots out to 100 yards real nice.

[@bilbo_gamers6417]

very interesting that you can shoot smokeless in a balloon head case. i have been trying to make brass cases for 22 long rifle for a while out of copper strip, and i always thought that balloon head stuff was only really good for black powder. i would love to make 380 acp or 5.56 balloon head or something on an arbor press and load up a magazine with it and see how it shoots. i bet i could make casings cheaper and easier than they do industrially. depending on what die you used for heading you wouldn't even need to put the case on a lathe. it would be like making 22... so interesting!

[@Everythingblackpowder]

Thank you. I was surprised it worked as well as it did

[@bilbo_gamers6417]

​​​​@@Everythingblackpowder Can I ask, do you know why balloon head casings fell out of favor? Can these cases not stand up to pressure like modern solid head can? It sounds like you have a lot of really valuable experience, like when you chose not to put smokeless at the bottom of the case at the primer level. do you know if balloon head casings are less tolerant of high pressures than solid head ones? i have heard this repeated a lot but i don't know if there is any basis for it - i mean, how often have you heard of a case blowing out from the back, or blowing the primer out? and primers are even thinner than the walls of a case. are there any resources that i could read about this that you would recommend? like, what material informed you to not put smokeless below the primer level? does that just come from experience and ballistics education?

[@Everythingblackpowder]

I tried loading smokeless in brass 12ga shotgun hulls some years and ran into that problem. I’ve never had a balloon head case separate but I’ve seen pictures of it.

[@bilbo_gamers6417]

@@Everythingblackpowder you mean primer blowout? interesting... also, id think case head separation wouldn't be much worse for balloon head just because the case head separation is because of a case wall failure. it reminds me of the old folded foil martini henry casings. those things actually rarely had case head separation even though the case head was just held on with solder.

[@mattferrell2696]

I've been playing around with the duplex load for the main reason that a percussion cap won't light HS-6. I was trying to duplicate a 45 Colt load in a 44 cap and ball. Saw your video and decided to revisit. I put 23% 4F black in a glass jar and 77% HS-6 (which is close in pressure and burn rate of Unique) By weight. I mixed the 2 like they would in a 45 Colt case on a trotting horse. I loaded 13 grains of this mix per chamber of my 1858 Remington. I compared to 25 grain charge of 3 f black and black powder only charge was still a little stronger. The point is when thoroughly mixed the low percentage of black still lights the smokeless

I have a suggestion you may love or hate. Half of tannerite is alumium powder. The other half, mixed 28:5 by weight with icing sugar, should burn perfectly cleanly, without soot, smoke or salts left behind. I'd love to test it, but can't here. Can you test that, in something you don't mind maybe breaking, at the end of a long piece of string? *EDIT:* I should probably mention that it's around 130 ft-lb per grain. That's probably very useful information when planning to do any testing of it. Don't go just tipping a teaspoonful of it into the case to see what happens, hey?

I have a solid base .575 ish 605gr Lyman mold that would probably be decent paper patched in that rifle. It’s kind of fun in my 58 caliber muzzleloaders.

[@cyclonetaylor7838]

Great video. In almost all black powder rifles over .40 cal I use ed to test them with my MAGGOB (make any gun go ba ng) load which was 14 gr. of Unique. My standard bullet for serious shooting I had an old Lyman .585213 and occasionally occasionally used a Lee .584 real bullet. My cases were Bell basic. I shot thousands of rounds and the primer pockets eventually got so worn out I had to Crazy Glug them into place. My dies were custom made for .585 bullets.

[@richarddean3154]

Thank you for doing this video. I wonder what degree of felt recoil is the product of the projectile's weight? It seems that propelling a very heavy bullet would increase the amount of pressure and bleed some of that pressure off in the form of recoil. Excellent video as always - I always learn something.

[@Everythingblackpowder]

Thank you

[@kirahund6711]

> I wonder what degree of felt recoil is the product of the projectile's weight? Conservation of momentum impulse of bullet + impulse of propellant gasses = -1 x impulse of rifle velocity of bullet x mass of bullet (+ Velocity of propellant gasses x Mass of propellant) = -1 x (velocity of rifle x mass of rifle) negative because rifle is moving in the opposite direction, can be omitted for simplicity 50% more bullet mass means 50% more recoil (assuming velocity and propellant etc woud stay the same. 50% more bullet velocity would increase the recoil by 50% , too. RECOIL IS PROPOTIONAL TO PROJECTILE WEIGHT AND also to PROJECTILE VELOCITY Increasing both by 41% at the same time would increase recoil by a factor of 1.41x 1.41 = 2 = 200% Lowering both mass and velocity of the bullet to 70% would reduce recoil to 0.7 x 0.7 = 49%, or about half the recoil. Slow and heavy means lots of recoil and comparatively low muzzle energy. Lightweight and fast means much less recoil for the same amount of muzzle energy. Subjectively felt recoil is, well... subjective, and dependent on a whole lot of other factors.

[@colinarmstrong1892]

Here in the UK there are plenty of shooters using Lovex D60 (same as 5744) in Sniders and Martini Henry's but without the black powder starter. I have some Bertram brass on its way for my Mk3 Snider so I may give it a go.

[@mfree80286]

Looking at the curves for 5744, you're probably getting up around 10-12K PSI not too quickly, but maintaining it. With that fiber wad, I'm going to guess that the 'tracer effect' and the heat transfer into the rifle are both the result of the same thing.... the curve and level are enough to compress that fiber wad and seal it against the case like a piston, and it's compressing the trapped air in the cartridge and igniting the lube with compression heating. Since that extra heat also bleeds into it's surroundings, the gun gets nice and toasty quicker.

[@robertstump4740]

I noted your use of LP primers. Remember when the JS and Pat Wolf book came out about loading the 45-70 TD and everyone jumped on the magnum primer bandwagon? I did some tests and got the worst MV and fouling with LRM primers. With identical loads, MV was DIY>CCI LP>Fed LPM>Fed LR>Win LRM and fouling ran the opposite direction. The milder primers gave me about 60 fps extra and 15% less fouling. Everyone has different rifles and protocols, but have you noticed this?

[@Everythingblackpowder]

I haven’t done extensive testing with magnum primers but in my experience they don’t make much of a difference. Also, with the primer situation being what it is nowadays we can’t afford to be too picky.
