Got a Lyman 429650 300gr mold this Christmas and finally got a chance to warm it up. As usual, casting with the Lyman was a charm. Nice crisp slugs fell from the blocks and hissed as they dropped into the water bucket. Great, now let's check them on the scale. 330, 330, 330, all consistently 30 grains over thier listed weight! And with lube and a check that's 339 grains!!
I like heavy, so it's not a huge deal provided I can get enough H110 behind it to shoot well out of my Super Redhawk. I'm just really shocked that it's casting so heavy!
Anyone else have Lyman molds that are this far off?
