Hello,
New to handloading/reloading. Just did my first batch of 9mm, around 100 rounds with 2 different formulas. I noticed that the Cartridge overall length was inconsistent and I'm wondering what factors might contribute to that.
Setup:
Brass: New Starline 9mm. (measured each one. All were pretty consistent at .750".
Bullets: Hornady, 115 RN FMJ
Powder: Acc7, and Power Pistol (2 different formulas, not used in at same time)
Primer: CCI 500 Small Pistol
Press: RCBS single stage (gifted to me used)
Dies: Lee Carbide set of 4. Used the gap, seat and crimp dies.
Primer setup: One batch I did on the press, one with a Lee primer tool. Primers did not feel proud using either method.
OAL was between 1.099 and 1.111
Measured after seating, if it was off by more than 0.005, I re-seated but that didn't change anything.
I know I'm probably being too picky, but I want to get things right and exact first before I decide how much variation I'm willing to live with.
Note, I've fired around 70 of these rounds. They fed and fired flawlessly in 2 pistols.
