When I cleaned the rifle after the first range trip, I got quite a bit of lead flakes out of it and accuracy was starting to deteriorate on the last group. I re-read Fermin Garza's article on firelapping and decided to give this one a treatment.

I don't have minus gauges, but slugging has worked for me in the past. I prepared 13 rounds of 44 with some WW gc bullets I had on hand but no gas check on them. These are 225gr 429215's, and put them over 3.7gr of Bullseye. I already had a 3/8" mild steel rod covered with vinyl from a sign shop in case I stuck a bullet, but none did. I fired 3 rounds and then bronze brushed the bore without a swabbing patch in between and repeated until I ran out of lap rounds.
I brushed it out again and shot some groups at 50 yds and a few rounds at a rock at 100. A total of about 10 more rounds. When I got home I cleaned the barrel and only found one speck of lead about like a grain of sand. I scrubbed the bore with some bronze wool I got at a stained glass shop used to de-solder joints with and soaked the bore in Kroil and left it. I think the leading problem is mostly solved, but will check it after the next range session to see.
Photo shown is the firelapped rounds, wasn't really trying for accurace, still put 8 of the 13 in a cluster at 25 yds. This would be an excellent load for little varmints
