Today if I get time I am going to make 6 test dummy cases. A fired 357 case(smokeless) is .379 dia. A sized case is .372 dia. I want to size my cases for consistency for use with the 3 guns I will be using. I also want to minimize how much of the case dia I size to.
At first I was thinking getting another sizer and having the sizing ring machine to a bigger dia. Then I remember the Lee factory crimp tool has a sizing ring built into it. It sizes the case to .378.
If all goes well with the test dummy rounds in the single action and the Rossi M92 rifle I will load 50 rounds to try in one single action pistol. If all 50 rounds can be shot in one pistol in one session without any issues I will load another 50 to try in the rifle.
I hope this works. It should help in sealing the chamber which is what I am aiming for over a fully sized .372 dia.
