Your 300fps over, by your way of thinking you must be on the ragged edge, [img]/ubbthreads/images/graemlins/blush.gif[/img] 100fps over your self impossed limit. (100fps for AI + 100 fps for 2" of barrel)
Same manual; 85gr bullet AA3100 46 gr max at 3308fps with a
I'm also 300fps over with my AI (100fps for AI + 200 fps for my extra 4" of barrel) [img]/ubbthreads/images/graemlins/cool.gif[/img]
Looks like you better reduce that load.
My 68 grain bergers that are running 3700 fps are milder than you load.
Nosler Manual #4; 3 listed powders in a standard 243 win, 70 gr bullet, break 3600fps in there 24" test barrel. My AI is only topping that by 100 fps even with my extra 4" of barrel.
I better juice that one up. [img]/ubbthreads/images/graemlins/wink.gif[/img]
I've got 5 reloads on the same brass, neck sized only, and they chamber just fine. [img]/ubbthreads/images/graemlins/grin.gif[/img]
Some barrels are faster than others, may-be you have a slow one.
