Re-Sizing Brass ?

BigV · Post by **BigV** » Mon Mar 24, 2008 2:29 pm

I realize that there is a need to clean and resize once (or twice) fired brass before re-loading it. But what about brass that is purchase new and has never been primed or shot. Do these still need to be resized before they can be reloaded?
I have some new 22-250 brass that I want to load up, but lubing and resizing is a pain that I don’t want to go through if I don’t need to.
Thanks!

It is best to at the very least run the case necks into an M die to ensure the bullet pull is consistent from round to round. I have seen new Starline 7.62x25 brass that would not chamber without full length resizing.

A friend and I bought (2000) 22-250 cases, we ran them in an M die and then loaded them, every one chambered fine and blew the heck out of prairie dogs

Check the length, too. You'll be amazed. Helpful to *slightly" chamfer the inside of the case mouth, just a touch to knock down any burrs.

I always resize and use a case length trimmer an all brass, new and used alike. Like Lefty Skywalker above me said, you'd be surprised at the variations in length AND squareness of the necks of new cases.
