I would like to know if any of you have an idea what is the actual size of .12 and .14 caliber bullets.

Example .17 has a bullet of 0.172
.22 has a bullet of 0.224, .270 has 0.277.

I would like to make some of these bullets, and I am looking for guidelines.

Any help would be much appreciated.

according to Mr. Eichelberger in his books:
the 10 calibers are .103
the 12 calibers are .123
the 14 calibers are .144

Thank you very.
I appreciate the quick reply.

Before I made any bullets I would want to know the actual groove depth of the barrel. I would not go by data unrelated to any commercial standard, like we have for the common calibers.

The good thing about us making our bullets on a CNC lathe is we can adjust the size anytime I wish.
