I going to start reloading for my 7mm magnum and was wondering how many times you guys are getting out of your belted cases and the best methods to go about it. I'm not going to be loading them hot, just moderate loads. Are you full length or neck sizing them? Which would be best for me? I'll be hunting whitetail with the gun which is a bolt-action model 70 winchester. I have never reloaded a belted case before, just my .308 win which I full length resize for a lever action rifle. Any help is much appreciated.
Thanks,
Sean
For most of my reloads, I size them only that amount required for the neck to properly grip the new bullet-(here I'm talking about cases that were alreadyfired in your rifle, and will go back into the chamber w/o any sizing at all). It only requires sizing about one bullet diameter from the mouth,(.28" to .30" of the neck).
What you must avoid doingis shoving the shoulder back when sizing, because if you do, it will move forward again when fired. And this amount of working the brass will cause early head separations, just like with a rimmed case such as the .303 British....
