Probably been discussed many times before?
I have a Czechmate and a CK Arms Open gun 9mm Major.
The CK Arms will accept a OAL of 1.150 and the CZ a 1.135. I got this by dropping a 1.150 OAL bullet into the CK Arms chamber and it rotated. The CZ needed a 1.135 OAL to rotate.
The 1.150 OAL I load to 7.0 Gr WAC, 124 Gr JHP, Small PP and assorted brass. About a 173 PF in my CK Arms.
I want to load the same for both.
Looking at loading 6.7 to 6.8 Gr WAC, 124 JHP. Small PP, assorted brass and would use for both. What are thoughts on this?
Or should I go the other way and ream the CZ so I can use 1.150 OAL for both?
I have a Chronograph, and I can get the PF, But what about pressure, as I have no way of measuring this? If I am under 1450 FPS am I ok with the pressure? Is there any correlation between the two?
Thanks in advance
