[QUOTE="MontanaRifleman, post: 803978, member: 11717"] If you want to engage in an objective exchange of facts then I'll oblige. First, 30 cal bullets have more mass than 7mm bullets of like shape so comparing grain to grain is not comparing apples to apples. To compare apples to like we'll compare the ballsically best bullets for each, i.e. the 284 180 hybrid and the 308 215 and 230 hybrids. 180, .674 G1, .345 G7 215, .696 G1, .356 G7 230, .743 G1, .380 G7 The 308 bullets have higher BC's If we are shooting out of the STW and RUM we are probably getting 3200 fps with the 180's and 3150 for the 215's and 3000 for the 230's At 1000 yds and 3000 ft elev the Vel, Energy and 10 mph Wind is 180, 2055, 1688, 3.92 MOA 215, 2047, 2000. 3.87 MOA 230, 1988, 2018, 3.85 MOA The external ballistics are a wash. The 308 bullets make bigger holes and hit harder and that's what counts. That's why a 7mm bullet is not as good as a 308 bullet. [/QUOTE]
