300 win mag neck size or full length size?

For those that load the 300 win mag do you neck or full length size and why?

Also, have read about full length dies causing a "donut" just above the belt. How many loads do you get out of your brass before it doesn't feed well?

Is anyone using Innovative Technologies die? http://www.larrywillis.com/

Always a good idea to FL brass used in game rifles...

to assure proper feeding & chambering....

Matt, call Larry and talk to him, he will answer any question's you have. He is a smart man and honest. His stuff is top notch.

Thanks for the replies.

Is feeding the primary reason to full length instead of neck size?

I understand fireforming and then using the neck sizer, just not sure I'm 100% clear on the full length sizing.

Should add that I only have one gun in each caliber, all bolts. So once my brass is fireformed it will only ever be shot in that chamber again.

Thanks again, Matt.

I FL size for hunting loads, I have experienced feeding issues with neck sized cases.

Hey Matt, yesterday there was a good set of dies for sale over on 6br.
