Estimated BC: .504 500 grain

[BoinLV]

I've been searching the forum and elsewhere online for hours, and realize the complexity and limitations of BC. I seem to recall some poster's range data with similar weight and caliber bullets in the past. Just looking for an educated guess to plug in to ballistic calculators for rough site-in and range purposes (peep sight).
Thanks in advance!

this a cast bullet? nose and base, and length

I calculated .29 when I made and shot my Mold.
That should put your bullet close.

I was going to say .26;to .27
I know my 480 gr are suppose to be .25 and my 600 gr are suppose to be .30 .

Might look here - Big 6x6 measured and computed years ago. The No Excuse is virtually the same bullet.

Thanks Guys! These of mine are Steve Brooks mold (by Dan at Bullshop), pure lead, flat nose. If that adds anything...

Thank you sabotloader! That's the post I was thinking of... should have entered "White" in the search box
