So this after 15 shots through my Winchester 1873 16 inch carbine chambered in 45 Colt.
Load was 40 grains Old E 2F black powder. 260 grain Accurate 454260 mold left as cast and run through a .459 lubrisizer using it to apply SPG in the big lube groove. Starline brass primed with Remington 2 1/2 large pistol primers. No separate compression just compressed with the boolit.
First time I shot some of these, I looked down the bore and swore I had mistaken some Unique loads ... so I loaded Nother 25 rounds here awhile back and today went and shot them.
First 10 just to see if they are as clean as I remembered them to be ... yepper ... so I shot the last 15 in slow fire motion and tried taking a picture as proof.
Not the best photo, but it shows the clean bore after 15 Old E powder in 2F size.
I am just stoked to say the least.
