First off I love this site. I've been here lurking for awhile but this is my first post. My first question is, are the manufacturers B.C.'s close to correct or not. For instance, Midway lists the .284 150gr Scirocco's B.C. at .515. Is this correct? If so that is alot of B.C. for a 150gr bullet. Sierra lists their 168gr Matchking at only .488. Seems like Swift might be pushing the pencil a little on the Scirocco's #'s.

How about the 162gr. Hornady A-Max? Hornady claims .625 for it. So, has anyone actually confirmed these B.C.'s with drop charts? If so, I'd be interested in knowing the results as I'll be working up loads shortly for a

7mm WSM. Also will a 1-9.5" twist barrel be enough to stabilize the A-MAX?
