[QUOTE="Lefty7mmstw, post: 1189136, member: 48043"] The case needs to index in the chamber squarely and too long of a case can cause it to wedge a bit if everything isn't perfectly true in both your action and chamber. I've noticed a good bit of difference between partial fl (or neck) and true fl sizing at times (one rifle of mine went from .5-.6 moa to about 1.5 moa with poorly sized brass) and at times it doesn't mean much at all. I still think you may have a load issue. If you don't have a load issue you likely have a squirrely barrel as B@G surmises. Try sizing the brass fl with the press cammed over first, then go with a load work-up in fl sized brass if that isn't enough. If neither work and you are doubly sure everything is tight and working well on your rifle, it may very well be time to put a different barrel on the rifle. [/QUOTE]
