Hello all,

I'm new to the forum, but have been lurking for a while. There's a lot of knowledge here!

I've been collecting Swede's for quite some time now. I've been forced to thin my herd, but I have a resonable representation of of the various models of the Mauser, including an m41B, an m94/14, a Husky m38, and a CG 63.

I've entered a precision rifle match and will be going "old school" with the 41. I need to work up some range cards, but I don't know the BC of the 139 grain service projectile. Does anyone have that number? I've done an internet search. There's a lot of talk about how high the BC is (one site had it as "insanely high!"), but no hard figures.

Thanks!

Dave

The 139gr Lapua Scenar BC is 0.615.

The 140gr. Berger [non-VLD] BC is 0.593.

Sorry I can't help more.

Thank you, gentlemen. The Scenar looks to be the same shape, so I'll go with that BC for now. I'll try to prove the numbers out this weekend.

Interesting site, Jebber. Thanks for the link.

Simpler version for smartphones too.
