Ive got a 6.5 grendel as well, and our local Atwood’s store had hornady eld Match bullets for $23/box. I bought a few boxes and brought them home to see how they short in my gun. It likes them, so I bought 8 more boxes. I figured that was way too cheap to leave behind.
Have you whacked any pigs with the eld bullets? I may have to do some experimenting as well, and maybe even remember to hit record.
I have a buddy that does a lot more pig shooting than I. He used the 123gr ELD-M out of the Grendel for a bit with pretty good results, although he stated that the way that the bullets reacted once inside tissue were inconsistent.
If all else fails, pop them in the head or neck and I'll bet you put them down with authority.
