I just picked up a new toy at a local pawn shop chambered in 7mm-08 Ackley Improved w/ a .312" neck (as nicely engraved on the barrel). I plan to use it as a stand rifle on our Texas whitetails as well as just play with this arrangement of rifle. It's built on a trued short Rem 700 action w/ a Holland recoil lug, 24" Shilen fluted heavy benchrest SS barrel, Sako style extractor, Shilen trigger all nicely bedded in an HS Precision stock. I am a very experieced handloader but have never dealt with a tight necked rifle. What method and tools (manufacturers too) are best utilized to get this thing shooting?

Ed,
My solution entails a lot of work, but turning the case necks too a thickness of .013" will solve your problem. Should also help improve accuracy. I hope this is of some help. Good luck.

Lapua makes .308 brass, I would get 100 of those, a Sinclair turner with 7mm mandrel, a Mititoyo ball end 90 degree micrometer.
