300 win mag neck size or full length size?

[mattri]

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.
