Swift A-frame ballistic coefficients

Sorry if this has been posted before, but is there a ballistic coefficient chart for Swift bullets accessible on the internet? I am particularly interested in the 400 grain .416 A-frame, and the 300 grain and 250 grain .375 A-frames.
Thanks,
Jim

(Based on QuickLoad tables)

400/.416 C = .367

250/.375 C = .285
300/.375 C = .325

No sweat, I was just in the right place at the right time. Most of the Q's get answered the way I would before I can get to them!

Glad to be of help.
