I have Lyman's 49th edition manual, a Lee 4 turret press, using barry's 115 gr FMJ RN, and Unique powder. For the 9mm, it shows the trim-to length to be .751". On the same page, there is a diagram that shows the case length as .754". I thought the .751" was to be the max? Why the discrepancy?
The Lyman is the only manual I have and the only 115 gr "recipe" they have is for Jacked HP. Does the grains or OAL change significantly between FMJ and JHP?
For the 147 recipe they list that as TMJ. The appendix says this is Totally Metal Jacket (Speer). Is this just speer's version of a FMJ? Would using a non speer bullet use the same specs?
I am looking for another manual to have as cross reference but not sure which to add.
Sorry if I jumped around, I thought I had a handle on this stuff but rereading things gave me pause.
Thanks in advance!
