Great review man. I’m a believer in hunting with these even for larger game at subsonic speeds. I’ve seen great results in my own testing.

[@BrassBashers]

Yeah I've always heard not to use subsonic when hunting with .300, but what's the difference in between say this round/a soft point bullets flying at 1000 fps and say a .357 soft point flying at 1000 fps?? Not much really, and I've had zero issues taking hogs with a .357.

@@TheFlyingZulu I'm talking about compared with the alternatives... like the various 200+ grain copper expanding offerings that expand 2-3× bigger than the sub-x. If you're interesting in ethical hunting, poking an itty bitty hole to get the bare minimum done, and perhaps letting them run away, is less than ideal.

I've been loading the Sub-X for 2 years now and have taken a lot of hogs with it. My load of CFE BLK is 11.8 gns with a CCI Mag primer which yields 1065 fps avg with an SD of 9 and 1 inch groups at 100 yds.

The load that works the best for me after weeks of testing using bolt action and several AR platforms in 300 blackout loaded with sub-x bullets is 7.8 gr of Lil Gun. I have harvested many wild hogs with that load with zero issues. Just bought a Iray Rico Bravo and that is a huge game changer for hog hunting when you own the night. My weapon of choice with this load and my new Thermal scope is my Rock River Arms in 300 BLK. I will be folding up wild hogs like cheap tents with this rig.

@@NelsonZAPTM I'm getting the same velocity with around 20 fps deviation depending on temperatures at the time, and the cold bore shot is always around 40 fps slower than the 3rd or 4th at 1050. Elevation will play a big role too.

[@DaleRoach-y7b]

I did a side by side comparison using H-110 and CFE BLK. Shooting from a 10.5 " suppressed barrel, the difference in SD was very apparent. With comparable velocities, the CFE BLK had SD of 6 with the H-110 showing SD ranging from 40 to 21. I live in an area with extremes of temperatures +90 to -20 and an elevation of just less than 3000 MSL. Because of that, I wanted a FPS in the 1050-1070 range. CFE BLK 12.3 grains was the sweet spot for me.

Extreme spread of 107fps SD of 38, this powder sucks for subs. Also your high at 1093fps that's on the border there, I would drop the charge to stay around 1030 - 1050.

I have had good luck using VihtaVuori N32C Tin Star since it still offers very good fill ratios with almost any bullet that I shoot from my Thompson .300 Whisper Super 14 barrel with anything from the 115gr Berger to the Lyman 190gr bullet. N32C is interesting since it does pretty much fills the case and almost all of my loads are subsonic with very consistent shot to shot velocities. Bob B

Personally I load ACME 265gn bullets over 9.37gn of Shooters World SOCOM & CCI#41. Fun fact, at 1050fps that bullet has more energy than a 357 magnum. As for expanding bullets, I never had good luck with the sub-x and prefer either Maker Bullets or Lehigh solid copper expanding bullets that do more of a flower expansion than a mushroom that the sub-x does.

Another person who loads, stated his best balance is the 125gr bullet and optimum speed for this rifle. I like the 147gr, but after I learn to load I may go with the 125 gr Super and try some others in sub.

50 to 75 yards is reasonable. With a 50 yard zero the come up is 23 moa at 200. You'll be wanting really consistent loads, a range finder and good dope. Please practice on paper first and know your limitations, wounding animals is bad sport.

Those are VERY expensive bullets to be shooting at steel. :( I totally get it for hunting but good gawd those things are way too expensive to throw at steel. I use mostly 147-150gr FMJ or pulled MIL bullets for subsonic shooting. They are cheap and easy to find and work well in my 300 BLK rifles. Most people think something as light at 150gr won't work subsonic .... but they do.

@@NelsonZAPTM I've used numerous different powders for 150 Subs. Trailboss works well but maxes out at about 850fps and won't cycle a semi. Its a bolt gun only powder. To cycle a semi I use 4198 and 4227. W296 also works but the first two are better.

I've been loading with both the Hornady and Dillion Progressive press for years, I can not for the life of me figure out why you guys never mount these things securely to a heavy bench, why on earth use the mounts that make the things wobble about like Joe Biden walking thru the oval office. You shouldn't have to hold it, mount it properly and start cranking, it is what they were made for.

These look like a great option to try out! My current sub sonic plinking load for 300 blk has been using Missouri Bullet Company's 238 grain powder coated bullets with 11.0 grains of Vihtavuori N120. It definitely helps having the 300 blk specific pmags for those missiles. With an average velocity of 1070 fps from the 10.5" barrel those rounds are carrying 600 ft lbs of energy with almost no recoil. It's fun!

Cfeblk should probably only be used if you have a picky gun that won’t cycle subs with other powders. it only works well with compressed loads which is annoying for some projectiles. It has the highest charge weights for less rounds per lb, and it generates more gas in the face than anything else. My gun runs 242gr coated cast with 7.5gr lilgun or 8.5gr h110 at 2.05oal. 8 lilgun and 9 h110 with 208elds at 2.15oal is another favorite. Good accuracy and SDs too.

@@donrichter3523 eh I don’t know if I would say it’s terrible, it just has a very limited application. Being: 300 blackout subsonic loads, ONLY for rifles that have trouble cycling subs, AND only if you are willing to screw around with overall length to insure compressed loads. Currently I use it for my bolt action 300blk, I make sure my loads are compressed and I get great accuracy with it. And gas in the face isn’t an issue with the bolt gun. But I probably won’t buy more when I use it up.

I've never been a fan of 300 Blackout but if it was coming out of a machine gun that changes everything... LOL Great video as always keepem coming brother!!!

[@Ultimatereloader]

It's way too much fun :)

[@DanielBoone337]

@@Ultimatereloader my neighbor is a SOT and he builds a bunch of guns so he has all the machine guns and stuff so I'm always over there tinkering on guns and I get to shoot the full auto stuff pretty often... You're 100% correct it's a ton of fun and I wish more people could take part in it!!!

Just picked up 100 of these bullets. Can't wait to load them for a trial run.

[@duggydo]

If you are so inclined, you should go hog hunting with that gun and those bullets. Would be an awesome video.

I love the Lehigh maximum expansion over 12.1 grains of CFE Blk.

[@JPUND]

Why don't you test 300 Blackout with a pistol length barrel?

[@Ultimatereloader]

Because I don’t have one- working on it 😎

[@Swampytheroot]

New to 300BO. No experience with suppressors. I bought 100ea 208 AMax and 220 MatchKing with a 16" upper. Looking for advice on suppressors

[@joshbrown1381]

What’s your application? Hunting, plinking, run&gun/training? Are you wanting something lightweight? Do you want something that is maximum suppression or just reduces the sound? Do you have other rifle cartridge firearms you want to suppress like 556/223 or .308?

[@guardianminifarm8005]

Well done. Interesting but very good results. Thanks.

[@edcjadon9002]

i'd be curious to see the ballistic results of that 190gr sub-x under various twist rates. 1x8" leaves a little bit to be desired when there are barrels out there pushing 1x5"

[@NelsonZAPTM]

1:8 should be fine for 190's. I've a 1:7, good up to 220. 240's are sideways at 200 yards.
