I had a MR pattern on a nice 280AI that weighed (IIRC) 40oz. It was a TANK. Sold the whole rifle. I believe it was a magnum fill.

But as for me and my house we will serve the Lord. Joshua 24:15
I can do all things through Christ who strengthens me. Phil. 4:13

I DON'T NEED A WSM AS I HAVE A WEATHERBY!
