[QUOTE="J E Custom, post: 1466905, member: 2736"] Just a follow up on the progress so far. I have been fire forming the brass and so far i have reached 3900 ft/sec with the 40 grain Ballistic tip in the 223 Lapua cases. accuracy is still ok for fire forming (.428 to .587 5 shot groups) so next i will try some 30 grain bullets at higher velocities to see if they will hold up in the 1 and 8 twist. the AI should bump velocities 100 to 200 ft/sec higher than the 223 cases so this is a good way to find the velocity limits if the bullets and continue fire forming my brass. The rifle still likes the 50 to 55 grain bullets while fire forming (Best Group so far has been a.193 five shot at 3520 ft/sec) so if it doesn't like the lighter bullets it's not all bad. the AI should be able to reach 3700 with this bullet. When I reach the limits of the bullet velocity in the 8 twist then I will have to decide what to shoot in the AI version. More to come J E CUSTOM [/QUOTE]
