[QUOTE="Crowe284, post: 1320909, member: 97064"] [b]Re: Anybody shooting 195 EOL in 7SAUM w/ H-1000?[/b] Did some more figuring after looking again at quick reference chart. This time I looked at base to ogive for the bullet itself: 180 VLDH-Base to ogive = .779 .779 - .243 (boat tail length) = .536 (bearing surface to ogive) Case base to neck shoulder junction 1.724 + .536 = 2.260 CBTO w/ bearing surface at neck shoulder junction. 175 Elite-Base to ogive = .762 .762-.207 (boat tail length)= .555 (bearing surface to ogive) Case base to neck shoulder junction 1.724 + .555 = 2.279 CBTO w/ bearing surface at neck shoulder junction So, as you can see from this example which I think is more appropriate because I was not using the true bearing surface to ogive length, you can see that from cartridge base to ogive, the 175 Elite is actually .019 LONGER than the 180 VLDH when the bearing surface is seated at neck shoulder junction and will remain longer seating bearing surface at any level above neck shoulder junction.
