I had a Buckmark Challenge with a 5.5 inch barrel red w/ silver flutes and a c-more railway. I sold it and bought a TS 2211 conversion and I couldnt do anywhere near as well as the Buckmark. I traded it to the guy I sold my Buckmark and Im getting the Buckmark back tomorrow. I think the Buckmark is the ultimate for Steel Challenge. Good triggers, lightweight, reliable and cheap. I dont ever remember a jam while I was shooting CCI Mini-Mags or Federal Premiums.
