[QUOTE="Len Backus, post: 29872, member: 1"] Speedbump You made some very helpful comments on "Big Sevens" over on the LRH Rifle Series thread. Here are my thoughts. I have next to zero experience turning necks and forming cases for wildcats. I have been approaching my goal of a super accurate rifle sort of from the bottom up. Never quite satisfied with each iteration in the process. Now I'd like to make a big jump up and work at it from the top down in terms of effort necessary to own and manage the cartridge combo selected. In a couple months I wll have gained experience with turning necks for a tighter necked version of my favored 7mm Dakota. I am now having it rebarelled as previously discussed. Then, by using a bushing die I hope to better control neck/bullet tension and reduce velocity spreads...and reduce vertical dispersion at 1k ranges. If I am comfortable with the marginal payback/effort result I will then proceed with a faster version of a 7mm cartridge. In choosing which cartridge to use, case prep and therefor case life (effort not cost) then gets to be a bigger factor. If my tight-necked 7mm Dakota justifies turning necks then I think the Lapua brass will be my choice for the "Big Seven". Sounds like you are getting only a few firings from the Rem brass? Plus, as you said, there is the "fun" factor to consider. [/QUOTE]
