[QUOTE="Bigstrap3, post: 506688, member: 29068"] I am currentelly building a 6.5x55 on a FN Mauser action. Is there any way to quantify how much I can reduce the pressure on the bolt bye changing from the above mentioned cartridge to a straighter case with a steeper shoulder? I understand that a straighter case with 'grab' the chamber walls better , not sure if this is a old wives tale or a significant thing. I am using a kreiger 28.25 inch varmit contour barrel in 1-8.8 twist. I was thinking of the A.I. as a way to get some more velocity and maybe reduce the bolt thrust.Any input would be appreciated thanks........... George [/QUOTE]
