Lighter brass means... What?

[Bayourambler]

Just examining my new Nosler brass for 300 win mag. and checking consistency . I have to say this is some quality looking stuff! Measures and weights very consistant. I'm comparing it to some new winchester 300 wm brass and the nosler is a good bit lighter than the winchester brass. What does this mean? Will it take a lil more powder? Will it have less life ? I haven't been reloading long and this is the some of the first new brass I fool with. I've been cutting my teeth on random brass givin to me. I hope I see improvements by using good brass. I feel i will!

Could be a difference in draw methods, groove/ pocket depth and alloy composition. Probably no big deal unless you're already redlining it.

IMX, Winchester Brass is always a bit heavier than anyone elses.

It seems to me that being externally the same, the interior volume would be a bit less, the walls and webbing would be a bit thicker, and it might very well outlast other brands.

Since I develop my loads in matched headstamp brass, I don't worry so much about over pressure from reduced volume.

I find that remington brass is heavy and quite stiff to resize. I actually jammed one in the die the other day!

Winchester 300WSM brass is, on average, 25 grains lighter than 300WSM Norma brass. Hornady 308 WIn Match runs about 8 grains lighter than Lapua 308 WIn. I don't know what you're goal is but I can tell you that if your brass is of the same head-stamp then you probably shouldn't get too caught up on what it weighs. If you want good hand-loads there are way more important things to worry about.
