Harry)---The A makes it possible to readily identify that it is not a B model.

Harry:

So far as we have been able to determine, it has no meaning with respect to the bullet design or size; it probably is an identifier for the machine or operator who made it. Only a few of those letters are helpful: a "U" prefix indicates a mould deliberately cut with an under-size cherry; an "S" suffix can mean the same (the #360271-S indicates a bullet originally designed to be sized to .360", cut for sizing to .357 or .358 ), or in at least one case I can't locate just now, "short" (for a bullet mould cherried to less depth than standard); and a suffix "ES" was used in one case to indicate an "extra-small" diameter.

Harry,
You'll also find some Lyman molds with an "R" stamped on them. These date to the early '70's when Lyman cleaned out their warehouse of returned and discontinued molds. My Dad bought a bunch of them at about $5.00 each, IIRC. Mostly they are just a bit bigger than was considered acceptable at the time. They were sold in an "as is" status.
