Anyone know of a site that publishes BCs for cast bullets? My interest at the moment is the RCBS 7mm-145-SIL #82150.

TIA,

Eddie

Thanks, Andrew.

Yes, thank you, Andrew.

Eddie, is the result of your calculations BC= .272 ?

This is the figure given in RCBS Cast Bullet Handbook.

I came up with .268. Pretty close considering I have only a micrometer and calipers to measure with.

Edited to change 298 to 268. I'm numerically dyslexic today.

HI,

I thank you for the site to get the BC of bullets I had a hard time and I am wondering if someone could help me out.THE WEIGHT OF THE BULLET IS 570, the medplate is .451 and the nose lenght , from the crimp groove to the top is .405. I hope someone will be able to give me a ball park figure of a BC.Over all lenght of the buyllet is 1.60 Thanks,Kev
