HSM 204 Ruger Brass

[Darryll]

Does anyone know who makes HSM 204 Ruger brass? I have some HSM 1x fired that I plan to reload along with some Hornady and I was wondering if they're the same, or if I'm going to have to do seperate load tryout. It sure would make things a lot easier if they're the same. Thanks in advance.

"any component change" should be cause for an initial reduction in powder charge by 10%" ..........an oldie but a goodie and for good reason!

Weigh them... if they weigh the same, they will load the same.

Or fill each case with a good flowing ball powder and weigh the charge.
