Got 2 61's from Taylors at WR last yr and have been shooting them all yr. (about 15-18 matches so far) and not had a single problem. I put in Treso nipps, smoothed out the internals, changed out the hammer spring to VTI replacement ones. I load 20gr 3f Ele, rnd ball (cast my own) and put lube, Hodgen BP lube, on top. They will function well for 50-60 rnds each without so much as a hickup. Will be getting another pair this yr. at WR 2005.
