I finally made my foray into loading 30-30 for my trusty Marlin.
I had started with new Winchester brass, and just for grins and giggles I ran them through the sizing die, then started to load them. Upon the first crimp attempt I could push the projectile into the case easily, and began adjusting it until I could not (Hornady FTX 160 grain .308 caliber). The die was not even camming the press over - so I was OK with it.
In checking the crimp that did work however, I find it looks deep, and in some cases it actually has the marks from the crimp die extruded from the brass at the case mouth!
Just to be sure I wasn't insane or blind, I took out two factory rounds to compare the crimps. The first is a Remington Corelok, and in that case of twenty rounds several had the same telltale die extrusions on the crimp. (picture of Remington next to Hornady).
Then, I compared a Federal Fusion round to the Hornady...they had a looser crimp.
Is my crimp too much? and, if this crimp is necessary to ensure no bullet setback (remember - its a tubular magazine on this beast)...what could I be doing wrong?
Thanks in advance!
Edited to change projectile diameter.
