The OAL of 1.075" will work with most JHP 124gr bullets and wit w231 powder
I can get a 3" to do 1063fps and a 5" 1166fps with a full load of powder.
It can get to a nice SD loading but nothing to brag about.

It does best in my weapons, .3-.4 grains above the starting load, for my target loads, that are quite accurate, with no feeding problems.

My 3" likes 4.2grs at 942fps for a light target loading with a 124 FMJ at 1.14"
