Depends in what you are hunting. For varmints the vmax 110 worms well but for deer sized game you need supersonic loads such as the TSX or black tips
110 VMAX, 110 Barnes Black Tip or the 125 Nosler. Somebody was making a 125g pink tip for a while that was 300blk specific, but I havent seen them for sale in a long time. There is a 125g SMK that is 300blk specific, but I dont know how it would work for hunting. I think most guys are using the 125g Nosler or 110g Barnes. Some guys on 300blktalk were/are experimenting with a ~150g something or other that is supposed to open up down to 1800FPS, but the problem is they are only getting about 2000 FPS at the muzzle so its realistically a ~100 yard round.
I'm not sure why these guys are talking the lightest .30 cal bullets you can find for sub-sonic, but I would start with 12-14 gr. of AA2015 behind a 230/240 SMK and work up. I don't know how high this will take you, you've only got to look at pressure signs. But, it's a relatively fast and therefore useful powder in low capacity situations, like the .300 BLK, so it should just about max you out in velocity as you reach case capacity. If you reach sonic velocity, it's not a big deal as AA2015 burns very fast and won't give 'double-ignition' issues.
( for Me )
Hunting High Vel. 300 BLK/30-221 . I have shot a lot of different bullets for hunting & best overall performance ( down range carry weight plus speed ) is the 125 weight bullet over the 110 weight . I really find the 125 Speer TNT's out-Perform the 110 V-max . And Even though the 125's TNT's are moving slower Vel. they carry better down range & hit harder .
300 BLK, You start using the 125 TNT's for coyotes & you will never look back .
For Heavier game & better penetration like small Deer etc. I got to vote for ( 130 grn. pointed soft point ) .
for ( Sub-Sonic Vel .hunting ) 220 grn. pointed soft points are my favorite . But subsonic-Vel. paper-plinking . I will load about anything from 175's to 190's also & shoot them .
.
Powder . H110 / Win.296 & Viht. 110

Tommy, we are using some hand cast 240gr lead bullets. Not exactly sure how they will do on expansion and such for hunting.
It depends on what you want. If you simply want to poke a .30 hole through something very quietly than, yes, throwing a 220 or 240g SMK down range would work and there are tons of loads for that. However those bullets WONT open up, tumble, fragment, etc.... because they are well below any speed threshold they are designed to do that in. The "advantage" in the 300BLK of sending light weight bullets down range is that some(110g black tips) are designed for 300blk and its speeds and some, through pure good fortune, will open up or fragment down to 1700-1800 fps and do a ton of damage. I wouldnt really say they are super light weight, I mean twice the weight of common .223 stuff moving only slightly slower, it still puts a good amount of energy on target.
If I was hunting it would be with a light weight for caliber bullet and not a heavy subsonic(except for maybe one of the 2 or 3 subsonics that are designed to open, but they are $1+ per bullet).
wont expand at all, will most likely pass right through. I think there is video somewhere of a guy doing water jug testing with the 245g Missouri Bullet Company lead bullets at 1000fps and it went straight through 20 milk jugs of water. If you could get the velocity up you would be better off.
Accurate 1680 is what I use for subsonic loads in the blackout. I shoot Sierra 220 and 240 grain. I use H110 for supersonic loads. I like the barnes 110 black tip, the Sierra 110 HP, and the Nosler 125 BT. I have shot 130, 150, 165, 200, 210. You can find loading info in the Sierra book under 300 Whisper. I have a 10.5" Noveske and a 16" CMMG. Shoot mainly subs out of the Noveske. W296 and V110 can also be used for supersonic loads.
rjacobs,
I was responding to the OP wanting subsonic. What is the point of putting a 110 gr. bullet downrange at 1050 fps when you can push a 240 gr. bullet at the same speed?
As others have pointed out, as well as yourself, you can push a 110 gr. bullet a lot faster than subsonic. But, the OP was looking for a subsonic load.

200 noslers with lil gun or 1680. They open a little but not a lot. Lehigh makes a fragmenting bullet in the 170 grain range but are single feed only in the blackout. Outlaw state bullets makes a blackout specific 220 subsonic bullet that works great as long as you can wait several months for them to manufacture them. They are great about emailing you with status update. I have been only running Lil gun or 1680 with nod going to lil gun. Good luck.
I 100% missed that he wanted subsonic stuff for hunting.
In that case stick with the Outlaw or Lehigh stuff at $1 a round as its the only subsonic stuff that will expand.
I agree with hunting at those velocities, the most important thing is is have bullets that expand/work.
the SMK blows for hunting at sub speeds... its like stabbing someone with a pencil for a wound channel...
you want flat points.. lead or 30-30 bullets
.308 SUBSONIC - Outlaw State Bullets LLC
Sierra Pro-Hunter Bullets 30 Cal (308 Diameter) 170 Grain Jacketed
Oregon Trail Trueshot Cast Bullets 30 Cal (309 Diameter) 170 Grain
That is a lot more reasonable than 110 or 125 gr. bullets of nearly the same style of manufacture as the 220/240 gr. It seems to me though a 220 SGK or SP-H will expand. Without costing yourself a buck a bullet. Still, more common bullets loaded down as you suggest would be just as easy.
I have to say shooting sub-sonic has always bothered me simply because no matter what, you start out with such limited energy. While not the biggest proponent of this round, I do accept it's capabilities. Lighter bullets can be pushed out pretty fast, and with a medium length barrel can cut down considerably on muzzle blast. I've seen this first hand with 6mm/6.5mm/7mm TCU and 7-30 Waters in TC Contender rifle length barrels. Even my 14" 7mm TCU isn't loud compared to other comparable energy rounds.
.
that's a good track record .
what was the POA on the deer generally when delivering those OSB Subs. ?
.
Most were high shoulder mass, and of course head shots. The sub load does lack teminal effects of hyperstatic shock so follow up shots most often required or a suppresed rimfire to finish. Thr OSB did anchor the majority where they stood. Great bullet but unless there is a legitimate need for silence standard velocity is the most humane method.
