Does anyone know or can guess (more or less that is) what the BC of the Northfork 375 caliber 270 gr bullet is? I looked at the website and it seems they are highly allergic to the matter!

I haven't shot it over the chrono at a distance to determine actual BC, but I load mine to 2770 fps, 2" high at 100 makes it 1" low at 200 yds consistently. Hornady shows their light magnum at 2870 fps (optimistic I think) 1.8 in. high at 100 dead on at 200, that's at 100 fps faster. This lacks a hell of a lot of being scientific, one of these days I'll set up both chronos and see how much difference between the muzzle and 100 yard and let you know.

I plugged the #'s you gave me in my PC program and it came out a BC of .210 . Seems kinda low. Are you sure? +2" at 100//// -1" at 200?

That's been my result, but bear in mind, I haven't shot too many 200 yard groups with the .375, and my groups are 2 1/2-3 inches at 200 so there is a margin of error involved. When I get to my brother's where I can set my stuff up I'll shoot over both chronos and find out.

Without some very sophisticated equipment I doubt if the results would be very accurate. My guess would be in the .320 range +/- 10. I've asked Mike about this and he doesn't seem interested in establishing the BC's for his bullets. I do know they work very well regardless of the BC.

My opinion exactly, no matter what the BC they are accurate and kill very well which is what a bullet does, kill game. If you measure the velocity loss between the 0 and 100 yard chronograph, this will give you a true BC, velocity loss is the function of BC we're interested in. Mike designed his bullets to work, not look pretty on paper.
