TESTED: Hornady Sub-X 190gr 300 Blackout

[@kevinwells4955]

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.

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.

I love the sub-x, load mine at 12.0 as well and have not had any issues. I use Berry’s for steel and they run good as well. Great review man!

[@sixtofive]

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!

[@ChilangoDios333]

I've used berry's 220 gr and they work great. But I wonder what is more terminally effective considering price. And if you loaded all to 1000fps Berry's 220gr that tumble Hornady 190 that expand Solid copper hollow points ~200gr Obviously the copper is giving you the best expansion but $1 per round is pricy I'm torn between the Hornady and the berry's

[@jgranger2002]

That's the best performance of this bullet I have seen. The other ones I have seen have really uneven expansion.

[@blancs3030]

I like using a lead cast 235 gr hollow point from noe molds. I use soft lead bhn maybe 10 with 10% of tin. It mushrooms really good.

[@texasbradley]

Very impressive projectile! There aren't many that will expand at that velocity despite claiming that. I've also found my lead cast hollow points mushroom quite well at subsonic speeds

[@rawtoe437]

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.

What velocity are you getting? I'm 8.3 grains for 1050 fps.

[@rawtoe437]

@@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.

[@GatorAaron]

I've tried the Sub-X and love them for use beyond steel. I've loaded with H110, CFE BLK, and Lil Gun. I've found better consistency with CFE BLK, but Lil Gun isn't bad either. I just got my hands on Shooter's World Socom and am inteto try out the sub loads with that as well. Funny I've been about to load more of these and saw this. Keep on testing!

Very nice I had the same results. You should also try the sig 205 sub tipped hunting rounds. I couldn’t get 1 round to stay in 2 gel blacks. They keep pushing.. Zero expansion or retention.

I agree with several other comments that a faster twist rate might be the ticket for the "gel exiting." It might help with expansion too. Another idea would be filing the nose of the HP bullet to give it more opening for fluid entrance. I would really be interested in the results of that.

All 3 deer he shot with subs all ran & could never be found, no blood trial or anything! All deer he hit with supers went down. I'm using 308 ar10 for deer but wnated to assemble a 300bo upper to use also mostly because I have a can on the way I can use on it.

[@mikeo4899]

I’m running a 1:5 twist barrel but what I would suggest is the 188 discrete ballistics Selous bullet. Your 190 load would be perfect for that 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.

[@DaleRoach-y7b]

I did some speed checks and not sure but this time at 11.3 grains, the velocity was right at the speed of sound. Dropped down to 11 grains of CFE and the velocity is more what I wanted.

[@bobs243imp]

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

I was able to trap one of four Sub-X 190 using 24” of damp corrugated cardboard (my poor boys ballistic gel), exiting at 20”, and found nearby. Expansion is a similar experience.

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.

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.
