300 BLK - 190gr Hornady SUB-X with N120 and 1680

[@DennRN]

Been hoping for more 300blk from you for too long now, this is probably my favorite of all your series, please keep them rolling in!

[@JohnnysReloadingBench]

Hopefully you caught my video a few months ago with the Speer Gold Dots kzbin.info/www/bejne/hKPdY2irmMuFqrc 300 Blackout is just pure fun and it will always be around my channel.

When I finally succumbed to peer pressure and reluctantly tried 300 blk, I watched every episode in the series at that time. I think he was almost done making vids. Saved me countless components. Oh and fell head over heals for the cartridge

[@bglenn2222]

@@JohnnysReloadingBench your MK262 series is what got me into reloading. Then I built a 300BO rifle and started loading that cartridge based on a lot that I learned from your channel. I have basically binge watched every video you've made and haven't missed an episode in months. Thanks again for the incredible content and the humor. My wallet hates you, but I've kept all my rifles fed during this drought.

I've loved these 190 Sub-X bullets. I've been loading them for the past year.

[@michaelg1164]

@@JohnnysReloadingBench Hey thank you for the time in putting this information out there. Was wondering if you’d be interested in seeing how the Sub x 175s work. With the 190s being harder to come by than varget, it would be interesting if the 175s could work. I’ve looked around online but not much out there for this.

[@shanerussell5448]

I’ve been using the 190 sub-x on deer out to 100 yards for 3 seasons now. I use accurate 1680 and run them right at 1050. They are absolutely the best bullet I’ve found for whitetail out of my 300 black. I tried supers with the 110 Barnes tac-tx and wasn’t getting reliable expansion. With the sub-x I’ve shot close to 10 whitetails, 2 150 plus pound bucks and none of the deer shot have went over 20 yards, most are DRT. As you’ve shown the sub-x performs like a nosler partition. Full frontal mushroom with a solid base driving deep. I’ve only recovered 1 bullet but it looked identical to the ones you shot through the gel. The recovered bullet was from a doe I shot head on in the center of the chest, the bullet traversed the entire length of her body and lodged in the far side of her back ham, maybe an 1” from exiting the rear of the deers ham. To say I was impressed was an understatement. I’ve now loaded over 700 sub-x’s and will hopefully have deer bullets for years to come.

[@John_Redcorn_]

Ive had an 8.5” setup layin around for 6 or 7 years. Still havent gotten around to loadinh for it. Lol.

[@doylethorn9251]

I have used the Hornady factory load for the 190 Sub-X for hogs and deer. My longest shot has been 52 yards. I get consistent nickel size exit wounds from broad side shots. All animals were down within 30 yards. The solid copper bullets do expand larger, however I get far less penetration with no exit on broad side shots. The animals also take much longer to go down. 50 to 100 yards. That's why I stick with Hornady Sub-X. It may also be noted that the Hornady load is the only 300 Blackout factory load that meets the F.B.I. performance requirements.

[@954dsm25psi]

That bug at about the 10m make on the redding box was just fascinated with your work

[@Super-Kuper]

I love that when you say it’s okay if it’s only a 50 yard accurate load and then shoot some of the tiniest subsonic 300blk groups you’ve ever put down

[@DavidWRankinJr]

One of the uses I have for the SUB-X is a 50 yard load for my AR Pistol (and eventually a short-barrel rifle I'm building). Having a loading that would hit a quarter at 50 yards has a lot of value, especially with AA1680 (considering how much I own of it for just that reason).

[@FMDad-dm5qo]

I probably would hold these rounds to 50-60 yards for hunting, but the platinum-tier accuracy of the Sub-X loads is still a huge plus, because it will allow for precise shot placement, which matters when your hunting bullet hits at 980 fps

I am in the UK and have a Remington 16" bolt action which I have blown the dust of the last couple of Years off and about to start loading. We are restricted to the components available and I am going to develop Sierra 220 and 135 projectiles, have some 125 SST that I think worked well. Got H110 and LilGun and a bit of RL7 to play with. Amongst a lot of left over .308 bullets too. Going to have some fun. Stay safe, and thanks again. Hope I can understand the notes I have scribbled down 🙂

Great video Johnny. I've still got some of those makers bullets that I bought 5 years ago after watching your video and you taking that doe with them. I also have been meaning to get some of those sub-x hornadys and just try them as well. You beat me to the punch. Love the accuracy of them though for sure and I will be trying them soon. Thanks for the great video. And thanks for teaching me how to reload 6 years ago.

[@blustripes4ever844]

I just found you Chanel I've been wanting to start reloading. I did with my dad as a kid. When you passed I got all his stuff. So I don't remember everything. So its good to watch and learn. I've hot a few hogs with that SUB-X. It puts them down quickly.

[@armeddiver]

Thank you for making this video. I have been toying with the idea of reloading, not for 300 BLK, but for 6.5 CM and 6 ARC. I am watching just about any channel that does reloading to learn as much as I can and to see what tools and space I will need if I do get into it. Your video was a huge help in showing the measurements that you take for your casings and the tools you are using for prepping the cases. My biggest concern is safety having gun powder in the house, etc. Again, thank you for the video. It was extremely informative.

[@christopherbehrmann5738]

Your my favorite channel on KZbin! Love the 300 blk ones.

[@1ordmorgu1]

I have just been building my first 300BLK SBR and prepping to load, first 300BLK loading. I came across Maker REX bullets and Sub-X and been trying to decide between them for starting place. Thanks so much for the great coverage here helping me decide to go with Maker! Also, as an ELD-X and ELD-M shooter those penetrating right thru were a shock at those velocities. Guess I have assumed better performance of those opening somewhat like other OTM bullets and the velocity just wont do it. Very good to lnow as I was thinking about ELD or GMX instead of Maker also.

[@bigald9560]

It definitely performs well, not necessarily as good as the copper, but still really good. And the accuracy...outstanding! Figuring it'll be around .5-.75 moa. For a 300 blk in that gun. That's awesome.

[@rjoetting7594]

I really enjoy your videos, there's a great amount of information on reloading, and I like the way you present it. Great work and keep it up. If in the future you want to have a little fun,try loading the sub-x in a .308 Winchester at supersonic levels and shoot it in your ballistic gel block. I've seen it before and the gel pretty much exploded.

[@BikerDash]

I'd actually be interested in seeing how well they hold up when shot at .300 Win Mag velocities. If the bullet holds together enough when shot at that speed, then you know it will reliably hold together when shot from a .308 Winchester.

I am currently getting it setup for hunting the way I like it. your channel as several others points out the value for the investment in these great firearms thank you for the content you make. With that being said, I have put together many PSA built lower receivers with BCA uppers, and they have been awesome! BCA is making great stuff and rifles that people are looking for in so many calibers, like he said the items are a great price! And they have great customer service they get it fixed and back in a week or less! I have people refer to Anderson AR-15s as "Poverty Ponys" and turn their noses up at PSA or Bear Creek so they can brag about what expensive things they have. Then later they can't outshoot the competition shooters at the range that are using standard ammo and standard firearms who are just having fun and socializing with other shooters I really enjoy seeing the Barney Fifes who have all the high-speed holster and gear and a stack of gun publications who talk a big game but when the old pros leave them in the dust!

208gr ELDx and N120 is my favorite range combo. Unimpressive accuracy but a fun range toy. Also switched to Viht powder from 1680 because it burns significantly clearer. Thanks for the food for thought!

[@echofoxtrotwhiskey1595]

How does N120 sound? I’ve heard the slower powders are louder, even suppressed.

[@justinrabbit2206]

@echofoxtrotwhiskey1595 it supresses well, but I'm also using a 16in barrel. I've also experimented with H110. It's cheaper, but the N120 performs better in both sound and accuracy. I'm getting around 3inch groups at 100yds. Dialed in to around 1020fps fwiw.

[@backnine]

I had a problem with 208 with 1680 from your video. I was testing before I obtained my can (9months). Shooting at the 20 ft line the bullets' were key holing. I found the bird cage flash suppressor was disturbing the bullet when it left the barrel. Took it off and no problem. They are fine with the can.

[@JohnnysReloadingBench]

That's really interesting!

[@backnine]

@@JohnnysReloadingBench It was driving me nut's. This is going back a minute. I think you were testing without the can with a 10.5 barrel. I had the same setup same load but was getting key holes. I was looking back at your video and the only difference was your mussel device. I think you had the 3 prong silencerco adapter. That big 208 at slow speed did not like that birdcage. Super sonic 125 g worked fine.

[@knitepoet]

Johnny, Using Li' Gun, I've worked down to a "max subsonic" load (~1070fps) in my 8.5" barrel and got comparable results in my 10% cleargel. I've also worked up to a "max" load in my 16" bbl, slightly over 1600fps. Spoke with the nice folks at Hornady and was told they haven't tested terminal performance over 1400fps. with them. Seeing what they'd do over 2k into gel should be entertaining. I haven't gotten around to gel testing my "max load" Once thing, for safety. I was taught, when working on developing a subsonic load, it's safer to start supersonic and working DOWN to your target velocity. You're normally not worried about being over-pressure with subsonic loads, and you're less likely to stick a bullet in the bore that way. I'd hate to see you have to do a video titled, "How to remove a stuck bullet from a 300BO bbl" 😉

[@prinzeugenvansovoyen732]

higher than 200 grain bullet weights in 300 blackout need a 1 in 7 twist rate for good stabilisation , 1 in 7 and 1 in 8 has high throat pressure therefor long throat cones and deep chamber throats are used to give the bullet freefloat inertia before hitting rifling to sa void a gas spike by the heavy projectiles hitting rifling with insufficient inertia to press themselves into the rifling, that causes a pressure spike til that heavy projectile gets moveing again, thats miliseconds but can be hundrets of PSI changes in burn rate and Pressure curve- also influences gas port pressure - dont stick heavy bullets out so far they almost touch the chamber throat - that free float is needed and engineered in for a good reason

[@mr.caveman7587]

Cavity Back makes a 195 gr subsonic copper bullet. I don't know how they would preform. I shoot their 125 gr supersonic bullet and absolutely love it. Always love seeing 300 blackout videos! Keep up the great work!

[@TweakRacer]

Wonder if the firmer gel blocks in this test made the Sub-X fold more. Maybe in softer gel blocks they would open more ideally. Add in their higher stability and accuracy... win.

[@DavidWRankinJr]

You don’t want to seat the SUB-X too shallow, because they don’t feed well in regular magazines. The temptation is to pull them out, but you really want to push them in far enough to get it up to the cantilever for “production” rounds.

[@marklacombe2671]

Currently working up a copper hunting round in 280ai. Got hornady cx, nosler e tips, barnes lrx and ttsx. Loading slower since pressure with copper solids seems to be a problem. Cross referenced loads and seemed hornady had a load starting 2 grains over max of hodgdons. Just seems you can really get in trouble.

[@texpatriot8462]

You shot a sub MOA 10 shot group at your target velocity with the Sub-X. I am not sure you need any more load development in 300 BO. If you want to hunt with that bullet, that is your load. Hornady has 220 Grain load data for a round nosed 220 bullet in 308. That might be an interesting use of the Sub-x.

[@hpfuhl]

My only issue is the testing distance for gel is always point blank. 10 feet is less than 10 yards. Most game even in archery hunting are taken at 15-25 yards or more. With .300 BLK sub I'd say maximum range of 50 yards. I'd like to see gel tests at those ranges so we can figure a maximum and minimum range.

[@CaptainCreampie69]

My factory Daniel defense 1 in 8 twist 10.3 inch rig shoots heavy subs just as well as my Q Honey Badger. I like them both but is the HB $1000 more gun than the DD? Absolutely not. I’d say $200-$300 more because I understand that they are lighter and that requires engineering but 50 percent more? Hell no. I love my Q guns and silencers but once you shoot them side by side there is no way someone can tell me the HB is 50 percent better. If it weighed half as much or magically had more velocity with a shorter barrel or perhaps was a sub moa gun all day no matter the rounds then ok. It however doesn’t do any of those. It weighs 26 percent less, is just a tiny bit more accurate (which for a CQB/pig gun isn’t a big deal) it also shoots supers slower and has proprietary replacement parts if something breaks. Which I don’t anticipate happening because its a quality gun but still…Good gun but not an epic gun. If i had to pick, id take the HB and sell my DD but only because it’s a little shorter and suits my needs as a home defense/car gun better, not because it necessarily is a better gun.

Has anyone shared my experience with the edge of the bullet tip catching in the barrel extension and causing a FTF? I’ve tried COAL’s from 2.045 - 2.175. Same issue. Seems that the tip catches and the bolt loses its grip on the case head, and closed on a the round while the tip remains stuck in the barrel extension. I have clear marks on the case heads where the bolt comes back and grabs the next round. I’ve increased powder to rule out under-gas. No issues with any other bullets I’ve used. Wilson Combat barrel.

When using a bullet seating die with taper crimp, can you separate out those two functions? Maybe adjust die depth to avoid crimping while bullet seating then come back with the bullet seating stem screwed way out but with the die adjusted for crimping? So bullet seating first then crimping on the second run. Any reason that wouldn't work?

“Next logical step would be do something goofy like shoot ‘em in 300 win mag or something” this is why we’re here!

I bet this bullet would be great in a 30/30. Just have to load 2. 1 in chamber 1 in tube mag. Wonder what the overall length would be.

I had trouble when seating bullets pushing the casing neck down and belling out the shoulder. shell wouldn't chamber..

I know this might sound silly, but it would be nice to see Sub-X out of a .308win. Just to see how it does. is it accurate? Will it retain weight at higher velocities? How does it expand at higher velocities?

[@Kyle-sr6jm]

If you have more velocity, a spitzer profile will have a better BC.

Wish you could make me some for hunting. I can’t seem to find any expanding bullets only target ammo.
