Now that the moulds are shipping, we need a results thread, so here we are.
I cast about 30 boolits last night and hope to fire them soon. I loaded some today, and ran into my first "issue". My assumption was this boolit form was designed to work specifically for the Marlin 336 in 30-30. I loaded some in 30-30 cases so that the crimp groove could be used. This is an overall length of @ 2.51. That length was not even close to chambering in my 1982 vintage Marlin 336 with microgroove. I found if I forced closed the action the rifle would "seat" the boolit to an overall length of 2.42. As you can see in the photo, this is well past the crimp groove. You can see the microgroove rifling engaging the ogive.

I also have a 1949 vintage 336 with Ballard style rifling. Obviously, this rifle has far more rounds through the barrel that the other rifle. The OAL this rifle would accept was 2.51 with a slight resistance. So the crimp groove could be used in ammo loaded for this rifle.
So I post this mainly as a FYI. Check your seating depth and make sure your rounds chamber before you load a bunch or drive all the way to the range and find they will not chamber.
