Lyman 9x19, 9x21 -- Why the difference?
Lyman 49th Edition
9x19
147 gr. TMJ
1.115" OAL
Max: AA#7, 7.2gr, 1014 fps, 29k CUP
9x21
147 gr. TMJ
1.169" OAL
Max: AA#7, 9.2gr, 1228 fps, 33k CUP
The Lyman manual mentions the above 9x21 load is their only load within SAAMI spec that meets IPSC major requirements. But why isn't this load mentioned in the 9x19 section? The only difference between these guys is brass OAL, nothing else...right?
Just curious. I'm only plinking with 115grainers myself right now i.e. don't worry, not trying to blow myself up, at least not right now.
