I just got my new .433-400 gr mold for my 444 Marlin from Mountain Molds.
As always, he's work is perfect.
Mold drop perfect bullets.
Here is a picture of the 400 gr bullet compared with my 350 gr MM.
With lube and GC.
Cast few, loaded with a small amont Norma 202, and went out shooting.
Loaded 30 grs N 202, and got 1168 fps out of the 22 in barrel.
Shot a group at 55 yards.
Got to say, I'm pretty pleased.
This is a good start.
