    Hunting season with 8" .300 Blackout

    I had a chance to take two deer this year with the .300 BO.

    Rifle specs:
    Stag sbr lower - BCM lower parts with ALG QMS trigger. No reason for the parts other than known quality, this is the only lower I've put together.
    Aero 8" upper - All Aero upper and bolt, BCM charging handle, AAC 51T Flash Hider
    Optic - DNZ one piece mount and Weaver V-3 (thanks to Lost River mentioning in another thread)
    Ammunition - Barnes 110 Tac TX
    Suppressor - AAC SDN 762

    Deer # 1 - Small (70lb) doe. Running shot broadside at about 45 yards in a field. 1 bullet to deer dropped it. Pass through but good damage during pass through and upon exit. This was unsuppressed and a buddy who was within 75 yards said it sounded like a shotgun or pistol. Scope set on 3x.

    Deer # 2 - Large Medium antlerless buck (120lb). Facing shot at 65 yards in a brushy cutover. Bullet entered chest on the left side, knicked right side of heart, wrecked right lung, knicked liver and lodged 4" into the right hindquarter. Viewing the entry of the chest from the inside of the deer was impressive, looked like one of my broadheads had made it. ETA - Recovered bullet weight 100.3 grains. Measurement across two petal side .639", one petal side .448"
    I haven't weighed or measured bullet, it only lost one of 4 petals. This was with the SDN 762 on the gun. Closest friend was 350 yards or so away and did not hear the shot. Scope set on 3x.

    My thoughts -
    I really like the handiness of this rifle on/in the stand and would be comfortable taking a shot on deer out to 100 yards. Looking forward to coyote hunting with it in the next few months. My 8yo also really enjoys shooting it. The collapsible stock and low power variable make this kid friendly.

    Pics of the antlerless buck and bullet.

    Gotta show this to my younger son. We set him up with 16-in. MGM .300 bbl on TC, has it zeroed for same load with Leupold 1.75-6X and he never got off his butt to go afield this season! This is our antlerless season through Friday, maybe he'll get motivated.

    Good shooting and report!

    So much like, so much jealousy over hunting land. Well done!

    Our go to kid caliber for years had been 7mm TCU, I have two Contenders setup as carbines in it. The commercial availability of performance .300BO has negated those though. I never had a 7mm bullet that performed like that Barnes did.
    I also have a 16" AAC Handi in .300 but that MGM barrel has been tempting me. The Contender triggers are so nice. Having a hard time ignoring the 6.5 Grendel thread though.

    Good luck to him!

    I'm a very lucky guy and know it. Extremely fortunate to have a small group of good friends who do all the heavy lifting to keep relationships good with neighbors and have an ear to the ground on available land. Doesn't hurt that as a club we've been hunting the same land since the 1940s and everyone but a couple of us own or live right in the midst of it. The few pieces of land that we lease are from family members or multi generation neighbors. The times are changing even for us, it's different than it was 20 years ago. People are aging out. I hope we can continue the magic through a couple more generations but even in rural Virginia it's not the same as it was 20 years ago.

    Why only out to 100 yards? I would think it would be good for 200 or 250, but i don't know.

    No reason other than I only shot it to 100 and am not certain of the drop heading further out. I set this rifle up for my 8yo and he is only consistent to around 60 yards. And to be honest I don't do as much shooting past 100 yards with low powered variables below 4x as I have in years past. Hunting season for deer is over for me so I'll be happy to see how far I can push it at the range, I'm really liking the Weaver V3.
