I have been working up a load for .45 ACP using AA#5 and West Coast 230 gr. plated RN.
After numerous trials, I am close to minimum charge - 7.6 gr
Now, suddenly I throw a new pistol and a chrony into the calculus.
The new pistol is a 1911 and it is having some "break-in" issues, but I do seem to get more misfeeds with my loads than with factory ammo. Stovepipe jams, and rounds that don't quite chamber all the way into battery.
The SIG is no help on this. It never malfunctions no matter what I feed it.
Yesterday, I chronoed my load at 7.6 grains. Velocity was low - average 804 fps. This is at or below minimum velocity depending on whose data you believe. Then again, it was 25 degrees yesterday - how much difference would the temperature make?
When it does feed and function, I like this load. It shoots nice.
But I am hesitant to load up a great massive pile of it, before I sort all this out. I am tempted to notch up the charge a little bit, if it could be a reliable function issue.
