I'm in need of a BC for a .30-40 Krag load. The bullet I'm using is an NOE 311-284 that weighs roughly 220 grs when cast out of my mystery metal (~ Lyman #2).

I do not know my exact muzzlevelocity but I may be able to run a few over the chrony except that the weather is really not looking good for that in the windows that are available to me. Does anyone have a known BC for this bullet, ore prehaps one that is similar (311299?).

Thanks,
Brent

NOE lists the BC's on their boolit drawing in the bottom, right side.

The Lyman No 3 Handbook lists:

The 311284 at .332 when weighing 210 grains.

The 311299 is claimed to be .377 at 200 grains.

So sorry, that NOE drawing was an older one and didn't have the BC listed.
