I also like Tanner moulds. They fit my Lyman handles just fine - however I have had to file the slots on one of the Tanner moulds to fit- no big deel- 3 seconds work.
I use wire strippers, the ones that look like plyers with little cuttouts for different size wire.
I grab the sprue at the ball's upper surface in a smaller (about 1/8" diameter cut-out), then while squeezing the strippers onto the ball's sprue, I twist the ball in a circle. Most times, the ball comes off the sprue without even a dimple, thus the ball's sprue, unlike on normal moulds, does NOT project from the surface of the ball and does not have to be orientated up. The ball can merely be taken from the bag and placed on the patch.
For match shooting, note, I always place the mould lines N & S, with the sprue cuttoff (if I can see it) oriented up. I even do this with smoothbore shooting RB's. Consistency wins.
These do look nice, don't they. .570's from a Lyman mould, casting .574" X .574". Sometimes one must read the ACTUAL measurement for the cast ball with a set of accurate calipers or micrometer.
