Re: neck turning and how its done
I'm not going to write an essay on turning but I can tell you it's not necessary to turn any factory case for a factory rifle. All cases are made well within the correct range for all dimensions. All turning can do is make an already sloppy fit worse.
The MAX loaded 7 mag neck diameter is .315". Subtract the bullet diameter of .284" = .031"/2 = .0155" SAAMI maximum neck thickness. Not likely you gonna find any cases any thicker than 13-14 thou. so there's nothing to turn so far as spec.s go.
