I used to have a similar problem with IMR4831 and 160g bullets. Dropping back a bit on the powder charge helped significantly. Or you may have to use different powders to get the velocity and case life you want. I get 3000fps easily using H1000 and H4831SC with North Fork 160g bullets.


There is a burr or something in my chamber that leaves light, half-inch long scratches in the cases. By counting the scratches I can accurately determine how many times a case has been chambered. Last time I had a case start to separate there were 18 such scratches.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
