I had a hunch you were going to say something like that. Over the years we've had remarkable success with 43.0 grains of RL15 and the 168 grain bullets, on the nature of 1/2 inch groups with sporter barrels and our indifferent benchrest technique. We're hunters, not target shooters, yet that 43.0 grain load works in all (5) of our rifles. On a hunch, I loaded some 150 grain Hornady SSTs with that same 43.0 grains and had my son run them through his Savage 10 FLP. He managed to put a 10-shot group into under 3/4 inch at 100 yards. Not too shabby.
I'm just wondering if that 1:10 twist will stabilize those 175 grain bullets better than it stabilizes those 168s? (and I realize I'm talking about the difference between eeenie-and-meeenie).
Sorry for the thread hi-jack.
