[QUOTE="BrentM, post: 948539, member: 61747"] Weird, just weird you guys are getting more velocity out of heavier bullets in the same case. I shoot 160 Matrix at 2730 out of a 24" savage. I will see how they do in a few weeks in the schneider 27", but i fully expect 2800. I struggle to see a 168 7mm pill out of the 284 going the same speed as a 140 in a 6.5-284. I guess I need educated on the physics of this. Does the 7mm handle more pressure and powder and therefore able to push a heavier pill at the same velocity? If so, I might lean toward a 280 AI for my next build to shoot 168-180. Although the BC of a 160 matrix is higher at .680 vs .617 of the 168, the 168 equals the 140 and at the same velocity will deliver more energy and buck the wind better. I like the wind bucking component mostly. [/QUOTE]
