Here is what I loaded... 9mm in assorted brass with CCI 500 primers, 4.0gr Bullseye and a lee 124gr tl tc bullet. Fired out of an Astra A-100 that was clean and had a shiney bore in it. After 150 rds the last 1 1/2" was almost a smoothbore, you could barely see any rifling in it. The bullets were cast from ww's with some tin thrown in to fill out the bullet then water dropped straight from the mold. They drop from the mold at .356 and I have not slugged the bore yet(my bad) and were lubed with LLA. Bullets were cast and lubed over a week ago.
I haven't had the time to get the chrono out and try not to shoot it yet, so I don't know the velocity. The barrel is drowning in a cup of 50/50 H2O2 and white vinegar making something hazardous that I will have to figure out where to dispose of later and lots of lead is coming out. My question, provided I have given all the pertinent info is either, why did it lead so bad or how do I prevent it the next time?
TIA, Mike
