I recently decided to begin reloading my own 9mm ammo.
My first attempts have been frustrating.
I purchased Accurate #7 powder and plated 115 grain round nose bullets.
According to Accurate's own load data guide:
Start load = 5.7 gr
Max load = 6.7 gr
COL = 1.140 in
I loaded 20 rounds each at 5.7, 5.9, 6.1 and 6.3 grains of powder.
None of these loads would cycle the slide - on 2 different guns.
So I loaded at 6.5, 6.7 and a couple at 6.9 grains.
6.5 gr - same failure to eject.
6.7 gr - cycled the action every time but slide failed to lock open on last round.
6.9 gr - cycled the action and the slide lock on last round.
BUT 6.9 gr is .2 gr above the max load.
The scale appears to be accurate.
Reading various threads on this site and others, I wonder if part of the problem is going with a 115 grain bullet in the first place - or if the COL should be reduced.
Any suggestions?
