View Full Version : B&M 311193 long pointy boat tail
Just picked up a B&M 311193 single cavity mould and handles at the Salem VA gun show. Any experience with it?
Here's a pix.
It's similar to the HBC .30 cal 200 gr. (a little longer, long taper and added boattail).
As soon as you can, please show us some groups that you have fired with that bullet.

Ben -
Good to hear from you!
This will take some time. Snow on the ground now. Will cast some of linotype tonight.
If I remember right, best results for the HBC were from HARD cast.
First cut. 182gr 0.311 as cast of 20:1 (700dF) (Had full pot, use most of in on .40 300gr.
Odd bullet is .30 HBC that Jay Downs designed and I did the cad work

Looks like it would be a sweet mold for 7.62x39 if it casts large enough diameter. The minimal bearing length due to the long tapered nose combined with the boat tail worries me a little though about the accuracy potential.
Oooooh, does are purdy boolits!

Interesting. If you go back through the old books from 1880 or so and forward you'll find the same general idea was tried by others. I wish you luck, but I wouldn't get my hopes too high. Were it me I'd be looking for perfect boolits, loaded with perfect alignment and seated to kiss the throat. With the center section alone being there to guide the boolit your alignment at the start will be critical. A fairly tight neck/chamber relation would help too.

EXACTLY.
My expectations are that it will be a real challange. (There's GOT to be a reason you don't see many pointy boattail cast bullets.
It's not too tough to get bullets as hard as copper. THen the challange is, as mentioned, perfect bullets, alignment, throat contact and so forth.
