Anyone know the crimp groove to meplat length on the MP 311-410? Getting ready to order the mold but the dimension's not listed and it's for several different applications, so I need to be sure about the protrusion.
Thanks - Ed <><

bump.
Wanting to use it in M1 Carbine, .30C Blackhawks, B53 .32-20 and S&W M1905/4 .32-20 as well as bolt guns in .30-30, .30-06, .300 WinMag, .303 Brit. I know it'll be about the same as my Lyman 311410 in most respects but wondering if the meplat vs the Lyman's RN will shorten it enough to work in the two .32-20s.
Any info appreciated.

Not what you wanted but some useful info about MP designs.

I will measure my MP 311410 tomorrow

Gamsek - Thanks very much. I can measure my blackhawk and 1905 cylinders and work out the differential. Looks like the MP 314-140 might be more likely to work, if they get 'em back in stock.
