Looking forward to seeing how this turns out! Also, thanks to those providing experiences with different bullets. I'm in the process of building a LH AR in 6X45 for the boys to use (20" 8 twist). Unless I get hamstrung by parts availability, I should have it up and running for them to use this fall. Right now I'm strongly leaning towards the 85gr Sierra and/or the 70gr Hammer for poking holes in deer.
