Anyone have a source for bc of 50 cal keith style bullets? I'm specifically looking at the no excuses 495, 460 and 420gr bullets.

My limited testing and research shows somewhere around. 18-.2 g1.

Thanks in advance.

Lyman Cast Bullet Handbook, 4th edition published BC's , not your profiles but you should be able to interpolate. I am surprised at the low .200 you mention. I would think that it should be higher...maybe .250, .260. But I know nothing of your velocity range.

495s are at 1275-1300

460 1350

420 are untested.

I shoot the No Excuses bullets in 45, 50 and 54 calibers. Never worried about BC. Best ml bullets in the industry.

The "worries about BC" is because I am wringing out a hawken and trying to ballpark the amount of elevation needed for long range. So far I'm shooting very well at the 300 yard line....but would like to save the lead and calculate the longer drops.

I would look at the best loads info from White Muzzleloading. It may not be exact, but it will get you in the ballpark. The bc’s are listed for each bullet.

Thank you. It looks like I'm close on my estimates.
