Designing the 2-diameter paper patch bullet.

[Distant Thunder]

Brian,

For your Browning .40-65 the 2-D PPB that Arnie just posted is an excellent choice. It was designed for that chamber.

My bullet was designed to get as much weight in a 18-twist compatible length of 1.250" so I could knock rams down with some confidence. So far it has been 100% on the rams, so far.

Arnie's .40-65 design is the bullet that really got the ball rolling on this whole 2-D PPB thing. If I had used Arnie's elliptical design I was afraid it would be too light in my 1.250 OAL for rams.
