I ordered the new mold (35-126M) from Accurate Molds on Saturday, and it arrived today (Wednesday)! I've had speedy service from Tom before, but this is astounding.
I've already cast some boolits with it, and the measurements are right where they should be. I'll PC and load some up tomorrow and make sure they chamber. With any luck I'll get to shoot a Super Steel match this Saturday and I'll report back.
