If my cases have a crush, bit a bit more than slight crush fit, will this create better acurract or worse? And will ther be any other kind of problems such as pressure? The reason I am asking is because I used a belted magnum collet resizer die and some of my cases are hard to chamber due to a crush fit.
Thanks

I think you need to readjust your full length sizing die so your amo will chamber a little easier.

In my book crush fit is not good. There are others that may chime in and say it works for them. Usually they claim the crush fit centers the case with the barrel more. Studies I've seen say it doesn't help and is slightly detrimental to accuracy. Benchresters DO NOT crush fit anymore. My personal observations are that I will never hunt with crush fit so why bother loading it and working the lugs of the gun more. And, it has given me different points of impact from properly sized ammo.

Now getting to the magnum collet sizer..which I have one. You do know that it only sizes the sides of the case? It really only needs to be used when chambering gets a bit difficult because of swelling above the belt. I use the collet sizer, then I size the case so that I bump the shoulder back about .002" for what I feel is the optimum fit with reliable feeding guaranteed. To each his own but just using the collet sizer as a sizing technique is really not what it's designed for.
