Hi Bricktop, The rifle started life as as a Nepalese Francotte Martini in 577/450. It was a wallhanger so I decided to make it usable (I'm not in to wallhangers). I bought an A&B blank 338 barrel and cut it half round half octagon, chambered it in 33 Winchester, and installed it on the action. The load was a Hornady 200 gr.sp at 2250fps.

Thats the quick story. A lot of alterations had to be made to the action to get it to work with a smokeless round.
