Ran across an interesting mold today that followed me home, a Lyman 37583. Turns out to be a .375 boolits that weighs in a 145 grains. Came in a black and white box with a pamphet on casting including that was printed 3-1-75. I figure it was meant as a gallery load boolit for the 38-55. Don't have one of those now, traded mine off and worked up to a 375 JDJ Encore. I have no idea how this bullet might perform from my rifle, it is a plain base with a single lube groove and a crimp groove, but I'm gonna try a few loads using AA#2, Unique and some milsurp 107 from J. Bartlett.
I found the mold at Toms Gun Shop in Rome Ga. Turns out he has some 15-20 molds of 1970's vintage, all new in the box. The ink has faded on the side panel, so it is difficult to read the numbers, but most of the molds appear to be 45's and 50's. I know these have been on his shelf for at least two years. I told him about the site here and gave him the URL, I hope he posts about these molds because I'm sure someone here could use or would want some of these. I recall looking these over a couple years back, and there being a few adjustable's in the group, but I couldn't say now what they were or if they are still there. I didn't get a card, so I don't have a phone number, but I'm sure "information" could give you one. His store hours are 8-5 Monday-Friday and 9-3 on Saturday EST.
