So..........
Probably should have cleaned the barrel of my new toy when I first got it (duh). It was shooting well and figured it was clean enough. Welp.
First two dry patches felt like I was pulling the patches through peanut butter. After I pulled those through I peeked down through the barrel and could physically see the buildup starting to seperate from the rifling.
View attachment 456050 Switched to 2x Hoppes soaked patches and let them soak for a few. You can actually see chunks of lead buildup on the patches.
View attachment 456052 After the patches starting coming through fairly clean I put 10 down range and then 10 more on paper.
View attachment 456053 Not counting the flier (it wasn't but I won't get into that) 9/10 landed in a neat little 0.35", MOA group at 32yds. Not too shabby for a 20ftlb .177 break barrel. Its officially too dark to keep testing but I have some very high hopes now
View attachment 456054 I'm curious if anyone has ever seen buildup like this on a break barrel? I pretty routinely pull a dry patch or 2 through every couple hundred shots so I haven't. I'm wondering if maybe someone decided to give slugs a try in this thing before I got my hands on it
