Hi Steve, mine is numbered 575213AM. Bullet weighs in at 572grns, has a dia. of .576", a conical base cavity and on each
side of the mould its stamped LYMAN 585. Have tried this bullet in both my 2 band (now sold) and in my Musketoon. They
load effortlessly down the Musketoon barrel with only minor effort required but took more effort to load in the 2 band.
Both guns shoot well with patched round ball so not too bothered at the moment but certainly this mould seems heavy at 572
grns compared to the usual 530 grn. I tried upping the load in increments of 5 grns between 50 and 80 grns with the 2 band
and it made no difference other than felt recoil started rattling the teeth at 80. Tim
Morning tac. 2 to 3" at 50m. Id be glad to just hit the target at the moment.!!!
