I’d like to hear if you use subsonic and have good success picking deer and pigs off feeders? Considering one for my daughter

Haven't used it for deer with subs, but works good for coyotes and javelina out to about 120 yards. For deer, I'd imagine something under 75 is perfectly fine for a clean kill just by looking at the energy numbers and the experience I've had with my .357 mag.

I have mine setup for deer at the moment, but I'm running 150gr Federal Fusions.

Edit: forgot to mention, it's a 16" barrel.

It does fine out to 150 on hogs I never use subs.

Maker Rex bullets are the way to go for subs. You will be blood tracking anything though. Just don’t expect anything to drop dead like supers do.

AR platform .300 BO is a great option with adjustable butt stock. (Like the one I have for sale)

I’m not afraid to shoot a pig with any caliber, so long as you stickem in the ear hole a 17hmr will do them in.
I have not shot a pig with a 300 blackout, but I have shot one with a 150 Game king in a 308 with a case full of trail boss running 1100 fps and it didn’t go a single step but again it was shot in the ear hole.

Someone needs to develop a flying ash tray in about a 200 grain weight for the 300 Bo so one can do exactly what your intended on doing, I thought there is some solids though that do some pretty big damage like the Leigh’s or whatever they are named..

I tried three times unsuccessfully. What I didn’t respect what the flight path of a subsonic load. You have like 10” of vertical travel to 100 yards. So if the game is at 70 yards you will shoot high with a 100 yard zero. Have zero of bullets flying over animals.

Another thing is while they are extremely quiet there is still enough noise to spook an animal at least with an AR. Flight time is .3 seconds that enough for the animal to get the jump on you adding to the challenge.

If you can shoot in 20-40 yards archey type range no reason it shouldn’t be successful. The heavy 300blk sub rounds are nearly identical to .45 acp at the muzzle.

I just... don't get the appeal of using 300blk subs for most hunting. Sure, bullet designs have come a long way, but it's hard to make up for the lost kinetic energy. And, as Scot points out, there are serious compromises in terms of external ballistics, too.

This is one of the times I don’t understand why people don’t embrace the 45 caliber offerings. A 300g hardcast limited to the same speed as a BO shooting subs is devastating on game at 100 yards. It’s also capable in the little 45 Colt case of going much faster in a good lever action, or the 458 SOCOM in a semi.

Full penetration but doesn’t expand. Then again it’s likely starting bigger than the BO will ever expand to.

Agree. I bought mine in 2011 when I believe it was the only offering other than 5.56 in AR. I wanted a bigger wound channel than 5.56 so it was a no brainer. Never even considered sub's. I've killed everything with it using 125 gr. SST's.

This is exactly why I quit messing around with sub’s because the 45 colts with a 300 gr hard cast will go through a deer length wise. My whole goal was to get several shots off on a group of pigs, it doesn’t seem to matter big boom or small one they always start running after the first shot.

I've killed a load of hogs with 190gr Sub-X projectiles. Haven't shot a deer but wouldn't hesitate out to 100 yards or so.

The group I hunt with has taken hundreds of hogs with 300 BLK supers. One year a guy tried subs and it was a dismal failure and the hogs were not recovered. Supers (inside 100 yards) with proper bullets put under 150 lb hogs down very well.... though if there is not a CNS shot, some hogs take a while to get the memo. Just like with most any non-magnum cartridge.

Personally I am not willing to give up half the velocity and 3/4 of the energy to hunt with. Certainly it can be done but it's over the line for me.

For me, it's mostly just so that I don't disturb the neighbors or deer over a coyote. I'm not against using a 45 colt or 45-70 with subs either, I just don't own one at the moment.

My son shoots it as well, so recoil is a factor when compared to a 458 SOCOM.

I night hunt with IR and 300 BO, 125 SST,110 Vmax, 135 FTX - all supers and no can. They work fine. Recoil isn't bad at all, little more than 223. Depending on how educated the hogs are, may or may not run at the sound. Do her a favor and run SUPERS. Subs were made for room clearing and self defense.

I haven’t had any problems using one.

As always it's all about shot placement and bullet choice. That said, the Blackout with subs is a 75yd combination in my opinion. Zero 1.5" high at 50yds and you will be GTG out to 75yds.. Bullets that actually kill well are going to be solid copper machined bullets like the Maker listed above or 198gr Lehigh Controlled Fracturing (sheds 3 large petals and the base normally shoots through the hog) or 194gr Maximum Expansion (expands and looks like a grappling hook).

If you're not worried about quiet, supersonic loads are the way to go. Most are more accurate than subs and will give you an honest 150yd range with very little additional recoil. There are several good bullet options here such as the Hornady 125gr SST, 135gr FTX, Federal Fusion 150gr, Barnes 110gr TAC-TX or Lehigh 115gr Controlled Chaos. Just stay away from the Winchester Deer Season Extreme Point in any caliber!!!

I tried .300 BLK subs when I got my first suppressor. I had this grand plan where I loaded the first round in the magazine a sub, and the rest supers. I took three shots on hogs at a feeder about 40 yards away and never found a spot of blood or hair or a dead pig. At the sound of the shot the hogs all scattered just like they do with supers. So I didn't see any reason to keep using subs and went to supers for hot hunting.

Last year I picked up a Ruger American Ranch in .300 BLK, set it up just for sub sonics using the Hornady Sub-X 190 gr. Saw two little doe walk up to me. Dropped the first one and the other on stood there, so I dropped her too. There were several other does with them that ran off at the first shot.

My other subsonic gun is a TC Contender with an 8" .44 mag barrel. I used some 400 gr hard cast subsonic's in it. I've shot two spike bucks with it. They ran off, but not far.

What issues have you seen with the winchesters? I had thought about getting some, but went federal instead.

Curious as well. I shoot those out of my 300 BO and they flatten pigs out to 150 yards. Was the only thing I could find during the ammo shortage but have had no reason to try anything else.

A good friend and very experienced hunter shot a big buck last season with the Deer Season Extreme Point .308 Win load from 75yds, first shot was well placed on the shoulder, deer ran off, he followed up and had to shoot it 4 more times as he tracked it and would catch up to it before he could get it on the ground. Only the last shot penetrated deep enough to get into the vitals. Bullets appeared to explode like a varmint bullet just under the skin.

I've shot plenty of pigs out to 150yds, some run, some are DRT, last year I shot a doe at 100yds with a 190gn subx, she ran about 20yds and tipped right over. I think as long as you shoot bullets that are meant for subsonic hunting use and you know your dope you should be good to go

My son shot this one about a month ago with a 300 blackout subsonic. It did the trick. Even though it worked great in this case I don’t like the subs for hunting. The trajectory is horrible. You need to know your distance exactly.

A well known Aussie hog hunter tried subs in the BO - results were terrible. And this guy is VERY capable hog hunter. His problem was the slow speed (lead) and trajectory. He normally hits running hogs with 308W.

Yeah the more I have read, the subs just don’t make sense to hunt with
