New Brass

[ljnowell]

Just want to point out to some of the poeple here making facetious remarks regarding resizing it, you are not always right. As I posted above, I have had both Winchester AND Starline brass that needed resized in 45 colt. Neither would hold a .452" bullet. In most cases yes, but only a fool speaks in absolutes, eventually it will make you look foolish.

Never FL size NEW brass. It's already sized too small to begin with. If you run it through a FL die it can and will push the shoulder back even farther. This will create more excess HS and the brass will have to stretch even futher to fit your chamber.

Huh? If it's already too small (and in the case of bottleneck cartridges, they are - they are about what you would get using a small-base sizing die), then sizing with a regular FL sizing die will only resize your neck without even touching the body and shoulder. Actually, resizing the neck is a good idea (at least with the Lapua brass I have bought), as they tend to be too tight. So, if you feel you must resize new brass, go ahead. Just be aware that you will not be changing the case headspace on new brass.
