according to my Oehler Ballistic software, the BC of the 130 gr Remington CL is .336

The .433 can't be right. Here is a site with some Ci's to compare. web page

Go to Rems site. Look up the remaining and muzzle velocites and interpolate the data into Pointblank.

.433 ???

Yep, that's so high I had to go to midway and check. It is higher than smoother bullets from speer or hornady.

I also checked the remington balistic charts from 1998. These gave me a BC of .333!!!

Apparently, uhh, well hmmm.
