New brass - different velocities than fire formed?

[QUOTE="Don Titus, post: 989624, member: 61851"] I've been working up an elk load for this fall in my 300 Win Mag and have decided on 73 gr. H4831sc behind 190 ABLR's velocity is around 2850 in used brass. Recently I've been shooting this load in new Nosler brass and my velocity is off between 100 and 150 fps and accuracy is about 1.5" at 100 yards versus under 1" with used brass. I've talked with several knowledgeable reloaders at my gun club and they say it stands to reason since new case expansion will reduce pressure to some extent and therefore drive the bullet just a bit slower. I intend to use the once fired cases for my hunt. Any thoughts on this? Don [/QUOTE]
