I got the Accurate Molds 43-335B for Christmas and got out to the range yesterday. I loaded 5 each of Alliant 2400 15.5, 16, and 16.4 grs. as well as IMR-3031 29grs. They were fired through a M78 Vetterli at 50 yards, cast of #2, sized .431, and lubed with 45/45/10, loaded in 38MM .348 brass. All loads shot pretty good and I was very pleased with my first try with this bullet. Next trip will include the M69 and 100yds test, I think I'll try the 16.4 load again, the first 3 were touching, the last 2 opened up a bit.
