Hi,
A few quick answers:
The photos referenced were not posted by me.
My issue is with the nose of the boolit slamming straight into the ramp in the frame and lodging there. The barrel does not seem to be part of the problem.
I size the boolits to .4525, which is .001 over barrel size.
I perform the plunk test on each and every round using the barrel.
I know my 8 round mags do not have the dimple. I think the stock 7 rounders do, but I'll have to check when I get home.
Thanks to Dan Cash for the offer! Must run now, but I'll PM you later.
John
