energy wise this round seems to split difference between a 357 mag carbine and a 30/30,, so given a decent bullet should be fine for inside 100 yard deer and pigs.
And there lies the rub,,, decent bullet.
I am new to non issue AR's built a 300,, shot it today,, Prefered remington 120 gr OTFB, Fiochi 220gr FMJ,, ( although 6 inches lower at 50 yards.) and Magtech 123gr FMJ,,, all produced ragged 1 hole groups at 50,, but different POI.
Other loads tried but not impressed with were the Hornady Sub X 190 gr, and S&B 200gr FMJ,,, those grouped about 3" at 50. Granted this is brand new barrel and groups did get tighter as I shot.
My original plan was to zero and blast with the S&B and use the 190 gr HDY as my main rounds,, but when I switched to the REM 120's and cut the 1 hole group made me reconsider. Soooo wondering which way to go,,, Obviously none of the rounds other than the HDY are meant for living targets.
Am waiting on can approval,,, Intended use of gun will be bugout truck gun, Fox, deer, pigs, all inside 100 meters. I do have a 300 BLK compensated reticle scope,, just started playing with it. Would like to lay up couple k rounds. Pretty much selling everything and want to only keep a couple handguns, a rifle and shotgun.
So for those who have hunted with 300 BLK what kinda ammo do you like ?
