Missouri Bullets BC Question

[KnotRight]

I am using Missouri Bullet 405 coated SWC and their 300 coated RN to shoot in my 45-70s. Trying to build a BC table for shooting past 100 yards and need to figure out the BCs for both bullets.

Any suggestions or help?

If it was me, I’d contact Missouri Bullet Co. They might be able to help.

Scattershot I did email them and they did not have any idea.

The older Lyman Cast Bullet manuals had BCs and velocity tables for a number of their designs. Not sure about the recent current edition. I'd bet you could find something that is close to the Missouri Bullet Company offerings to get you close.

I have the old Lyman Cast Bullet Handbook, if you could post a pic of your bullets, I may be able to find something close.
