I'm really interested to see what Variable gets with his 10.5" Grendel pushing the 85gr Sierra's with a faster powder. 31 grains of faster powder behind an 85gr projectile should send it out at a respectable velocity. It wouldn't surprise me to see 2600fps with that combo. I still think 10.5" is a bit short for an LE blaster, especially for bigger guys, which is why I would lean to 12.5" so you could at least have a mid-length handguard, and still suppress with one of the micro-sized cans.
