must I full length size new brass?

sdoc · #1 11-09-2011, 08:33 PM

i just bought a 7mm stw and 2 bags of new brass do i need to full length size the new brass? or can i just neck size it? reason i ask is because it would save me some money not buying a full length die, as i already bought a competition bullet seating die and would just buy a neck sizer. thanks!

You do not need to size the brass at all until it has been fired. Prime it, dump your powder load, and seat your bullet. That is all that is needed!

100% not true size the brass no matter who made it and do a full prep.

Go with what he said. Though, I know you do not have to re-size them. I never have, I don't prep the case until it has been fired once. But I am sure that it would not hurt, and most likely even help, for you to re-size them.

If its a hunting or f-class rifle I would suggest getting them and using them. If its a bench rest gun the I have no experience with that.
