300 Blk and hunting: first hand experiences

Hi all, have any of you hunted with the 300 blk or seen the results of a hunt firsthand (or lack of results) using supersonic ammo? What ranges and grain/type of bullet? Deer and hogs are what I shoot mainly. I don't hunt from blinds and spend most of my hunting time in or around thick brush and do not want to buy a larger platform than ar15. I like the idea of a heavier grain projectile and I can't see shooting farther than 200 yards on an animal. I own 3 AR 223/556 and want to convert the barrel on the lightest one to 300 blk 16". I am not going to buy a new upper, mag, or bcg and I reload and am not worried about the price of the ammo. No 6.8, 6.5, .450, 308, 30RAR, etc. please. Tell me about your results, thanks!
 
I've taken about a dozen deer with my old 38-55 Winchester. With factory ammo, that's only got about 1350 ft/lbs of muzzle energy at the barrel. The 300 AAC has about the same muzzle energy with a bullet of about half the mass (125gr vs 255gr), but will shoot flatter. It should also retain plenty of punch (enough for deer/hogs) out to a few hundred yards.

Ought to be just dandy for taking deer/hogs with appropriate bullets and supersonic loads at the ranges you're talking about.
 
I built a 16" 300 BO for just what you are talking about. I have one Coyote and one deer. I used the Nosler 125 grain BT Hunting at 2380 fps. The Coyote was hit at 225 yards, DRT, and the deer at 90 yards, DRT. Was happy with the performance. Wish I could give you more, but I just built this rig last spring.
 
I built a 16" 300 BO specifically to shoot hogs on my next trek to visit my best friend in East Texas. I used a Stag lower, pSA nic-boron BCG, PSA upper and flip sights, Midwest Ind Gen 2 SS slim rail and a Rainier Select Stainless polygon rifled medium weight barrel, topped with a Veltor extended compensator. The rifle. Shoots like a dream (carbine gas and Spikes T1 buffer) as it has a different feel than a 5.56. When it hits a can of chicken soup at 100 yards (15.5 W 296 with pulled GI 147 gr bullets) fun things happen. In the future I plan to expand my chicken soup hunting to include a Texas hog or two, or three and have full confidence the300 BO will do just fine.
 
I used a Hornady 125 gr SST over 18.5 grains of Lil Gun to take a 100 pound whitetail doe, the range was 154 yards. The round appeared to expand well,
Leaving a basketball sized hematoma in the impact side rib age, and a golf ball sized exit through the shoulder blade. The deer ran about 50yards. My only problem was that I hit her high and she didn't leave a blood trail for around 15 yards. Once the blood trail was found, it was easy to follow.

I like the 300, and look forward to hunting with it next year.
 
Thanks guys, I just bought another lower and can't decide between 6.5 Grendel and 300blk. Maybe I should just buy another lower and do both.

Click to expand...
well that's a silly statement. Of course you should!!! lol.
And post them to a new threads for builds and testing, etc so we can all be smarter!
 
Well, you know, you COULD get a third lower and build a 6.8 spc. That would round things out nicely:). Ain't preaching, just say'n!
 
well my 6.5 grendel is pretty much amazing with deer and could outperform the 300 BLK any day of the week and twice on sunday...


...mad yet?...


... good, now I can give you some theoretical advice since I don't actually own a BLK. the 300 BLK has almost identical ballistics to the 7.62x39mm... go over to the hunting forums at SKS boards and you will see page after page of dead deer and hogs taken by 7.62x39. the 300 BLK is limited in ammunition choices because most makers make heavy subsonic ammo rather than lighter hunting ammo loaded to supersonic speeds. if you load it yourself, the BLK can perform very well as a deer rifle though 200 yards may be pushing it unless you shoot enough to have a very good understanding of your trajectory.
 
Oh no sir, not mad at all. I think the 300blk build will be a light one for walking (very dense brush, senderos, trails and roads) or possibly for spotlighting hogs. I don't anticipate shooting over 150 yards with it. I just have SO much .223 brass and 308 caliber bullets, and I realize that any of these ventures requires reloading, which I already do. The 6.5 will be for blinds and 1000 yard shooting. Thanks for all help, I'll let you know how both perform. Now if I could only figure out how to post pics with an iPhone.
 
Couple of guys around here use them on hogs and deer and they seemed to work well if loaded with good ammo. Most guys are handloading 110gr TTSX to full power and are having very good results out to about 150 yards or a little more. Some other loads with bullets like Nosler partition and Hornady SST doesn't seem to do as well.

I'm having a 300BLK built on my old 223 caliber Remington Model 7 with 1-8" twist for use with the TTSX load and 220gr subsonic load with a can. It will be my dedicated hog gun.
 
I am almost done with building a PSA based mutt 300blk and can't wait to give those piggies a hard time!! I'm thinking for bullets i'll mostly be using Sierra ProHunter 125gr since I already have several hundred for my .308win.
