[QUOTE="SpencerSS, post: 520530, member: 32793"] There's a problem or two with comparisons in this group. There are too many variables being changed. For an accurate comparison you need two cart.s with the same volume, with the same components (powder, primer, bullet...), loaded to the same pressure (and see which uses less powder, or load with the same powder charge and see which produces the higher velocity). The only thing that should be different is the case shape, since that is the variable being tested. 300WSM vs 300WM is closest. still not a great comparison. The WSSMs are different volume, higher pressure than their usual comparative partners. The 270WSM is closer to the 270 Wby mag, etc... [/QUOTE]
