Thanks Dave,

This is kind a hybrid project, fitting savage .457 upper on the old 20mm frame.
Had the barrel with and adapter on the frame some time ago and it was interesting.

Upper block ready.

Fits ok, now need to make some modifications to the barrel. Going to have locking lugs on the barrel and bolt.

very nice machine work.. especially the hollowing of the loading area.

Thanks Rob,

Got to test the rifle and shoots ok, 134mm 10 shot group at 200m from bipod and no back rest.

384gr soft point goes 276m/s at 220bar and 304m/s at 300bar so I'm ok with that.
Need to do something about the recoil, slightly too much bounce from the hammer.

Fantastic stuff! The craftsmanship looks outstanding as usual. That is a beast for sure but also looks cool.
