Watched my son knock another 200 pound boar on his butt at 97 meters with the 300 BLK last night with Pulsar Thermal. 110 gr Barnes X going about 2200fps. I know 300 BLK doesnt get much love here but it got her done again.
I am a diehard Grendel guy and also have ARC barrels from Odin!The little grendel is definitely an over achiever. It's also one of the most accurate cartridges I've ever played around with. Some day I will have to build a super light weight bolt gun in the grendel. No recoil to speak of from an ar either. Mine is a heavy barrel Les Baer and has a brake and the x hair doesn't even move at all when shooting it. It never fails to put a smile on my face. Being a Br shooter for over 30 yrs I have become sissified to recoil. 99% of ammo I shoot is done free recoil and the 6.5 grendel is a sweet heart. If you stick to the Alexander load data your brass will last a long time and so will the bolt. I have a spare bolt just in case but have never needed it. I'm looking at doing a 6arc next just to have another 6mm.
