[QUOTE="bobnob, post: 699492, member: 47596"] Good question! I guess all the variables need to be calculated of course. It would depend in part on the differences in the friction bearing area and weight difference. I can't call on much relevant experience to help except the following; Once when I was working up loads for a 270 I was experimenting with 130, 140 and 150g bullets, and all three weights were of different brands. I used identical charges - 59g - of AR2213/H4831. In the case of all three different bullets the speed was a near identical average of 2970fps with a near identical point of impact. Not directly relevant to your query but relative somewhere on the periphery. [/QUOTE]
