Down my way,on the "redneck riviera",some hunting clubs,with shooting houses on 1/2 -1A plots,where the long shots are <150yds, have outlawed the use of 300BLK's. All length bbls included.
I suspect the ballistics "guru" of the club has come up with this rule from what he has read on the interweb.
Personally,I would never try to kill game animals using a heavy/long bullet that is subsonic. Some say they will quickly destabilize when hitting the animal,and tumble. Some say the bullet will "pencil through" not doing adequate tissue damage. (?????)
I guess that I feel that the bad rep that has stuck on the 300BLK has come from two basic things. #1. Hunters trying to kill animals at the ranges,and with the bullets,at the speeds,that they should not be shooting. If you check the ballistics tables,there are some bullets that fly very well out of the 16" 300BLK. Some will give you a 250yd range that still delivers enough energy,and the bullet still opens well enough,to kill any deer and the 200yd hogs with a shoulder shot.
#2. Shot placement . . . NOTHING will take the place of this. I told a "hunter" several days ago,if you cannot put the bullet where it is supposed to be with your 300BLK,you most likely can't with your 30-06 either.
I have been shooting the 300BLK for about 6 years now. I bought my brass already processed. It was cheap. It works great given different head stamps.
My RARR will put 5 shots into .300" -- .400" at 50yds all day,any day. --- SAWMAN
