Ballistic Coefficient chart

[Wayne S]

Is there a chart or a listings of the BC of cast bullets ?? I know RCBS lists the BC of theirs, and at one time there was a chart that you matched the bullet as close as possible the the shapes listed. Just wondering if something new was out there??

Lyman cast boolet handbook. The back section has extensive data for their stuff.

I haven't look at them in decades but Du Pont you to put out "Exterior Ballistic Charts" by Wallace H. Case and Edgar Beugless, Ballistic Entineers of the Burnside Laboratory. You might be able to find those on amazon.com

Thanks everyone, the two links will be fun to play with on cold rainy days :bigsmyl2:. The bullets in question are Saeco's RG-4 or # 301, # 311, # 073 and the 071/soon to be GB 7 bore rider/Hunter.
So far I've figured that the 073 is somewhere between .270 & .285

Again, thanks

Lee has the BC listed for each of their moulds too. Though I wonder how much BC matters on handgun loads.

Load from a disc has a printable chart, however, I don't have a printer on this computer. Maybe another member could print it and e-mail you copy?

When you are trying to keep recoil low and hit IHMSA full size rams, full size chickens and 1/2 size rams at 220 yards one needs accucary {don't whan the bullet to become un-stable at 175 yds because it started to slow OR arrive on target W/O enough energy to knock over a 55-60 # ram}
