    Default Favorite 300 BLK bullet ~100-120 grains?

    I've been shooting some Sellier and Bellot 110 grain TRGX copper bullets but want to try something else for deer.

    Most of the Hornady choices are the 110 gr. V-Max which is a varmint bullet and may not get much penetration. They also make a CX which is copper but I am looking for a jacketed lead bullet.

    Lehigh makes a 110 gr. Controlled Chaos bullet that is supposed to get penetration plus has pedals that sheer off early. I've used much heavier Controlled Chaos bullets and they performed pretty well on the few deer I have shot with them, even at subsonic velocities.

    Does anyone have a recommendation for a tried and true deer bullet for the 300 BLK in the 100 to 120 grain range? I want to shoot around 2200 to 2300 fps. and can reload if I need to but complete cartridges is what I'd prefer.

    I shoot the Barnes VOR-TX 120 TAC-TX and they are deadly and accurate AF, midway has them for $35/box right now

    My experience with typical "varmit" bullets for the 308 in 300 blackout is fairly positive. They have plenty of penetration and make a huge mess internally. Great for pigs. However, if you are shooting deer in the shoulder area, don't expect an exit wound and therefore don't expect a blood trail. Barnes TSX 110 is my choice for deer as it does seem to go through and make plenty of destruction along the way.

    Look up black butterfly ammo. He loads some 150gr hornady interlocks among other loads. He is local as well.

    Thanks for the replies.

    The VOR-TX is another copper bullet. I'm hoping to find a jacketed lead bullet.

    I need to keep the weight lower than 120 grains because this gun is used for heavy subsonic and lighter supersonic without adjustment. I don't want a cartridge that requires tweaking the gas port.

    Anything above 110gr will suffer from steep velocity loss when used supersonic. The heavier projectiles are longer. They stick deeper into the case stealing room for powder. There is no way around this. As the gr weight goes up this velocity loss becomes quite dramatic.

    The 110gr vmax is a varmint bullet at 308 speeds. 300blk speeds with the same bullet are much much slower. All because there is significantly less room for powder in the 300blk case and chamber versus 308. It performs more like a common cup and core projectile at 300blk speeds.

    The THE projectile is the Barnes 110gr tac-tx FB. It is the one that had the most testing spent on it by the US gov. It's the one selected for performance in the 300blk chamber. It is not a 308 projectile used outside of its ideal performance envelope. It was designed specifically for use in the 300blk at 300blk velocities. It completely sucks in the 308 because of this.

    If you are focused on killing 2 legged or 4 legged targets--it's the one you want.

    Federal fusion for super sonic, but I think they are 150 grains.
    Hornady 190 grain for subs.

    110grain nosler varmagedon kills nicely. Shot a couple pigs and a couple deer. All dropped where they were.

    I've got some of the Barnes 110 gr TAC-TX and some Fiocci 125 gr SSTs on the way. I love the SSTs in the 123 gr. 6.5 Grendel and in 165 gr. .308. Not sure how well they'll do with the muzzle velocity of a 10.5" BLK barrel. I'm hoping the supersonic 125 gr SSTs don't beat the gun up too badly. I'm not interested in swapping buffers or adjusting the gas block when I change ammo. It took me a while to tweak this gun to reliably kick out hulls with subs and not beat the receiver up with supers.

    I shoot the same bullet in 150gr 308, pass thru on every deer I have shot with my waypoint pencil hole going in, golf ball size hole coming out and if they don’t drop they leak,,,,, a lot, I have shot the 130 gr sst out of my 270 for yrs and I have never had a pass thru they usually run about 10-20 yds and expire. But you can forget a blood trail with the sst

    I tried sst 125 and vmax 110’s in water jugs. No test on meat yet. 16” barrel at 25 yds. 110 caught in 3rd jug. Dissentigrated. 125 went through 4 and kept going. Was out of jugs to try 5.

    I know that you're not looking for 150gr, but I'll attest to the fact that PSA's cheap AAC 150gr ballistic tip will land a sub 1/2" 3-shot group out of an 18" Ruger American. (Confirmed at 103.7m.)

    I've yet to shoot a deer with it, but where my stand is positioned, it'll be about a 50 yard shot; child's play...

    In reality, with the range capabilities of 300BO, I'm of the option "shot placement over bullet type." If I'm hunting distances greater than the round, I'd just pick up another rifle.

    Having said all that, with what's stated above regarding the 300BO specific bullets, my interests are piqued as to how they'd perform.

    Are you seeing pass through on deer? I have seen 2 shot with different ammo from a 300BO but no exit hole.

    Yes the Barnes ammo that I’m using has great weight retention. And I shoot my deer square in the shoulder. With that being said, all my shots are within 100 yds

    I got the Barnes VOR-TX 110 gr. and the Fiocchi 125 grain SSTs and was able to chrono them out of a 10.5 suppressed AR barrel. I get 2240 average for the 110 grain and 2030 average with the 125 grain. It surprised me that at 200 yards, the 125 grains hit maybe an inch lower than the 110 gr bullets. The 125 grain cartridges cycle fine in the AR but pile the brass farther behind me.

    I also found some Lehigh 110 grain Controlled Chaos cartridges in my ammo bag that I didn't realize I had. I shot a big doe yesterday evening with one of those and it performed as advertised. It was a steep angle high shoulder shot from a bow stand. I hung around the processor to assess the damage. The four "petals" sheared off and went in different directions and the base core pushed through and out the far elbow. The lungs were pudding and a lot of the shoulder bones were shattered, one leg was floppy. Instead of a DRT, she somehow ran maybe 100 yards with no blood trail. I'd probably still be looking for her this morning if my little noodle dog didn't find her. I might stick to lung shots for situations where I really need a blood trail.

    There are some interesting gel tests online for the AAC Sabre Blade Black Tip 110 gr out of a short barrel. I’ve been loading up on it for defensive purposes. I use my 12” Grendel for under 200 yd deer applications.
