When = trying to deduce blow from jack angle, there is a little latitude in = that there is a range in which it will still work pretty well. Also, on = well-used butts, there may be some cavitation just from compaction, = which will mean either a little more lost motion, or shortening the blow = slightly from its original design. Anyway, that's why I suggested = combining it with the amount of dip required for full function, before = settling on a final blow distance. Bob=20 Thank you!
