Maybe you folks could give me some advice. My b-in-law and I have several rifles of various brands (Rem,Ruger,Win,Sav,Wby Van, etc.)in standard big game calibers. We have been able to tweak loads and get good consistent 1 minute accuracy out just about all of them. B-in-law bought a Mod.700 26" heavy barrel .308 that will shoot a 2" 3 shot group at 200 yards only occasionally on its best days. Usually much worse. The magazine won't handle much over a 2.815 COAL round. To get a Nosler 150 BT to touch the rifling takes a COAL of 3.000. Is this acceptable? Can this rifle be expected to be accurate if the projectile has to almost jump out of the case to engage the rifling? By the way, the Nosler BT is its most accurate hunting bullet, 168 MK maybe a little better.
