Kirby,
I agree completely that past 600 YDS a heavier bullet absolutely is the way to go. Less drop, TOF, and more energy. But I just don't trust myself to shoot anything other than paper that far. I just built a Warbird with a Broughton tube finished to 31". I'm getting an avg. 3709 fps with no pressure from 165 gr. Sciroccos. Averaging 3" at 500 Yds and a little more than 8" at 1000. I have the utmost respect for you guys taking game past 600, but it's just too far for me. From 600 YDS down, fast and (relatively) light seems, at least to me, to fly flatter and hit harder. I killed 5 deer last season between 350 and 525 yards and the one at 525 had me a little nervous. If Lazz takes this to production, I won't be buying one of his rifles, but I'd like to get ahold of a reamer and some brass.
