Hey cast boolit brethren.
I'm noticing a disturbing trend of streaks building up in the bore for the first few inches ahead of the chamber. There appears to be a corresponding loss of accuracy that accompanies this fouling. I'm wondering if anyone else has noticed this.
I'm using Eastwood powder, copper vein mostly, and pretty sure I'm cooking long enough. Minimum 400F, (tested with a thermometer) and minimum 20 minutes after wet out.
This is in 45 colt, with loads from mild to moderately wild.
Any thoughts? The deposits are a PITA to remove, more so than the minimal lead deposits I've dealt with from similar loads with conventional lubed boolits.
