356242/358242 OAL in 9x19?

[Divil]

Hello,

I made an inert cartridge with a .356 sized 358242 boolit with an OAL of 1.060. It fed like butter in my new Kimber 9mm. Is this OAL of 1.060 (with the understanding that + or - a few thousandths variance) too short for this boolit? My Lyman 49th manual lists 1.065 as the OAL but I am not sure if this is the maximum or minimum OAL Lyman is listing here? I would prefer to cook up a test batch and 1.060 for a function test but I don’t want to knowingly load some kind of compressed combination with nasty pressures.

Thanks,
Divil

I size my my NOE 359242 (the Lyman clone) to .357 and load to a COAL of 1.065. It's my go-to for 9MM and works fine in all the 9's I load for. You are going to have some "Press Variation" to COAL no matter what you do and a couple of thousands +/- is not an issue.
