Dirty bore shooting

[Eric Johanen]

Have been thinking about this. I've gotten close with the 50-70 standard Shiloh chamber using BACO .494 500 grain slick patched to .500 dia and OE 1.5 powder. Seating depth set to chamber just short of the fouling at the chamber mouth. I want to use a busing die to set the case mouth for a snug fit with a bullet patched to around .498 and see how it fly's. 45-70 using a tapered patched bullet that fits snug in the fired brass and is small enough to clear the chamber mouth fouling and lately the 44-77 with Orville's chamber dimensions patched to .439 seated just deep enough to clear the fouling for up to 10 shots with no fouling control. Tests are planned using a bullet patched to .437 when the weather improves. What is working for the rest of you fellow's? Let's not work alone and share the information that works. A check can be made of my progress on this board and am wondering what steps I'm missing and can add to my loading system to be successful.
