[QUOTE="DJ Fergus, post: 1673978, member: 93895"] Go to jbm tradjectory calculator and punch in the numbers for a 180 eld 7mm @2860fps and then punch in the numbers for a 147 eld @ 3050fps and compare the two in ft/lbs energy & wind drift out to 1000yds. 2860 with the 180 can be attained in 7mm RM, 280, 7mm rsaum, 7mm, wsm with a 26" barrel & correct powders. 3050 with a 147 gr can be attained in 6.5-06, 6.5-284, & 6.5 prc with correct powders & 26" barrel. Recoil when calculated for the two bullets @ given velocities will be only slightly more for the 180 vs the 147 in same weight rifles. I own rifles that shoot both of those bullets. The reason for my response is because I am embarking on building a medium weight rifle in either a 6.5-284, 6.5prc or 284 Winchester ( match reamer).
