[QUOTE="West Calamus, post: 2132460, member: 110228"] Caliber 25-06: Hornaday brass wt. sorted to + or - .02gn. 176 gn.; versus R-P 270 range brass annealed, full length re-sized too 25-06 and trimmed, and sorted + or - .2 196 gn. I know the heavier brass has less room for the same charge compared to the lighter brass. So the question is heavier or lighter brass better for powder expansion , life of brass difference, less charge for same velocity in the heavier brass? The hornaday brass has about 9 firing on it and won't last forever so playing with the idea of using the resized 270 cases. ( don't worry I don't have a 270 so head stamp is not a problem). With such a large weight difference I thought it would be a good test to find out what the differences in brass weight equate to. Just asking for some heads up on what to expect.
