Pressure issues, need some help

[mgunderson]

Each cartridge that has small and large primer options, has its own adjustment for adjusting data. Small primer data to large primer always is a reduction in propellant.

You understated the adjustment and didn't get hurt. Count yourself lucky. We don't always get this lucky. Some cartridges are closer to 1/2 grain, but the internet doesn't get this stuff right very often.

The internet comments do not have the safety check that published data does. Do you trust us enough to stake your face on it?

I appreciate the post and hope we help others avoid the issues many of us ( me included) have experienced along the way.

I’m learning. I just assumed all but 3 grains below their max would have been safe

A better approach to have is to start at the minimum and work up, provided all else is as per the load data.

Out of curiosity, how did you get that expanded case out of the chamber ?
