Might have helped if I had mentioned the caliber
Yes, it's 9mm. I have been meaning to pick up some Alox, but my local shop always seems to be out
Did you clean out all of the copper in the barrel before you started shooting lead?
Yes, the barrel has been soaked and scrubbed within an inch of it's life.
It's a Beretta 92FS
Also where is the leading occurring in your barrel? More at the muzzle end or more toward the chamber?
With the 4.4 load it was along the whole length, with 3.8 it seems to be more towards the middle.
Any thoughts on where to find .357 9mm bullets? Just use .357s or what?
