I try to get my share of practice in but that practice doesn't involve firing 10 or more rounds back to back.
People talk about certain cartridges being barrel burners -but more often than not they are refering to competition shooting.
A 6.5 grendel would be a barrel burner if there was a competition where you pounded out 30 shots in a row.
6.5stw as an absolute top end
6.5 wsm would rate very high for me as a longrange hunting cartridge
6.5 -06 or 6.5-06 ackley very high on the list
6.5-284 sure can't go wrong there and load developement would probably take you ten minutes
I have 4000+ rounds down the tube on my Grendel gas gun, MOST of them in strings of 30+. (Whats the fun in a semiauto AR if you aren't going to shoot lots of rounds?).
It still shoots under sub 1/2 MOA with at least 2 different loads.
I know guys who shoot theirs on full auto and haven't replaced barrels yet after thousands of rounds.
I don't think it matters how you shoot the Grendel, there just isn't enough powder capacity to be a barrel burner by any reasonable definition.
Several of the others may be, if used as target rounds where long strings are being shot.
