OK, with a long hiatus, I have news. I have the rifle. It shoots awesome. I am currently tinkering with the trigger to get it smoothed out because the break-in trigger job (3000+ rounds down range) is way too darned expensive even with crappy .243 ammo. I'm loving the way the gun handles and groups hornaday factory loaded 58 grain v-max. I will be building some 55 grain nosler rounds to see if the rifle will still shoot as tight. Flipping through the Nosler book I ran into some interesting information... The .243 55 grain projectile has a better coefficient than the .22 cal slug of the same weight. And in 22-250, velocity was about sixes between .243 and 22-250. Hence my whole reason for the .243 Ar. With the 55 grain bullet, I essentially have a 22-250 with a fat stack of 20 round magazines. And hand loading for the beast means that I can afford to shoot it every bit as cheaply as my .223 AR.
