Well fellers, the MFH is finished. Last night I put the finishing touches on the HP attachement.
The first pic is of the full assembly. I solved the problem of a variable length HP cavity by making an adjustable sleeve. This screws up and down the adjustable nose punch and varies cavity depth. So, I'm able to vary length of nose as well as length of cavity and lock them in with setscrews. An L shaped notch in the top of the hex sleeve retains the cavity pin during testing.
The second pic is of the finished product. At left are two .35 Rems. One loaded with a 254 grain solid and one with a 240 grain HP. The two bullets below/center are a 313 grain HP and a 240 grain HP. Don't know as I can use a 313 grain .35 HP but I can make one.
It was a fun project./beagle
