I'll find some TAC to try out. The R-P was fired in my M77 already, so it was formed before it hit my sizing die. I was planning to set the head right at the lands, just touching.
Yeah, the 24" bushmaster upper over a timney drop in trigger makes a nice rifle, and sharp with the boyds laminate furniture. I have to fit a different scope for bench shooting, but I have one or two kicking around. Not something I want to carry around all day, but for setting up to snipe 'yotes I think it'll work just fine if I can dial in a 300yd round.
