preping new unfired brass?

[seez52]

I just bought a sack of brand new unprimed brass for my .222, it sure is purdy. Never used any virgin brass before. What's the general rule for loading brand new stuff like this? Does it need to be sized or anything?

I thought I'd chamfer the case mouth on all of them first, but noticed some are a little dinged and not quite round. Any general procedures for starting with fresh brass?

I'd suggest you size, trim, and chamfer before loading. Some of the case mouths won't be round as they easily get bent in shipping, and you'll likely find some length variations as well. I'm not saying this is necessary, but I do it. The more consistancy you can get from shot to shot, the better accuracy you'll enjoy.

+ 1 to what Greg said. Always size, trim, and chamfer new brass.

Kind regards,
