Just purchased a set of RCBS dies for my 300, have seen and read different things online ( if itís on the internet it must be true) what kind of case life are you folks getting out of yours? Do you full length resize? I have never loaded a belted case before, thanks

It depends on whose brass with me. Remington brass is good for 3-4 reloads and Norma/Weatherby brass is closer to 8 or 9.  I full length resize every other re load.   :)

I get similar case life for Weatherby/Norma brass to what badsection describes above. I dont use Remington cases because the only batch of them I tried was horribly inconsistent, and the case volume was so small the starting loads from two manuals were compressed.

I neck size two or three times and then partial-full-length size (just enough to bump back the shoulder and make the cases chamber normally again). Then it's just lather, rinse, repeat.

Thanks for the responses. I plan on using Weatherby and Hornady brass.

I FL size every time. I've gotten 6 or 7 reloads from Hornady brass in 7mm-08 and 270. But with Hornady brass in 300 Wby I'm already getting loose primer pockets after 3 reloads.

I use Weatherby brass in my 257Wby and I'm on reload#8 of this lot.

Weatherby/Norma will definitely last longer but Hornady can give you a few good reloads, just be aware case volume is quite a bit lower with Hornady/Remington cases than Weatherby.

If you have never loaded for a belted mag before be sure to set your sizing die to headspace off the shoulder and not the belt. This will give you much better case life.
