Drew thanks. Mec bars are known to throw light shot drops and depending on the size and antimony that would be about right and would only take a few pellets to make 1 oz.

The powder is .4 grs apart and if the LUP conversion is close to PSI that would be close to SAMMI.

The hull diameter of .821 behind the rim is greatly enlarged, and unless the chamber opening was that large the only way it could get that size is if the gun opened when fired.
