[QUOTE="sable tireur, post: 1724995, member: 27307"] I think you're a little bit short on velocity compared to what my Bartleins are shooting. I have a node between 3250 and 3300... But it might just be your barrel, I don't know since I don't shoot X-Calibers. Be careful running those lighter bullets in a 1:7" twist at high velocities. The RPMs will have a negative effect on those bullets. The 90 gr. Berger VLD is losing a little BC even with the 7" twist. The 95s will not do well because of the additional length. Use the Berger Stability Calculator to check your numbers. [/QUOTE]
