Anybody Shooting .327 Fed. Mag. In A Rifle?

[Dixiejack]

I have a Ruger No.3 and I am thinking about having it rebarreled in .327 Federal Magnum shooting 150 to 165 grain cast bullets. This rifle is going to be a 200 yd. target rifle. I'm thinking that a 1:12 twist would give me the most accuracy.

What I am looking for is some smokeless load suggestions.

All my other shooters are BP and other than .22RF, I haven't owned a target rifle that I've shot anything but BP in.

I have a WTB ad posted here, but I will mention that I am looking for a factory stock set off a Ruger No.1.
