[QUOTE="J E Custom, post: 519015, member: 2736"] I see how You came up with the capacity and understand. But I never count the neck because It is being used by the bullet and only adds unusable space. I normally subtract one caliber of neck as an average and it works out very close to what you can actually get in a case. A longer body will contribute more to case capacity than neck length, and that's what I was referring to when I said that the 7WSM would hold more powder than the 7/300 wsm because of the .054 Thousandths longer body. I find it very hard to get much more than 72 Grains of powder in the 7 WSM and would suspect that the 7/300 would be around 68 grains If one caliber of bullet engagement is used. and if less is used then it kind of defeats the purpose of a longer neck except for reaching the lands. Again ; I have nothing against the 7/300, I just don't see the need when a 7 WSM is available with no fuss, other than to have something different. Just an opinion. J E CUSTOM [/QUOTE]
