The dimensions of the uncut blank for the gun.... I could not remember. And cm is a bit much
mm maybe, me and the metric system.... I should have taken more time before I posted. I could not recall the starting point. 50mm x 50mm x 1500mm. I knew the length, could remember the height.
So if it is made to an oval shape, we lose material in the height a little. If it stayed at 50mm, the band channel could be 10mm and you lose 1/5 of the barrels strength. But changing the shape of the barrel, I'm not sure what the effects are.
So as far as the channel covering the entire band. I don't thing it would have too. And I'm not sure it can once the gun is re-shaped to be oval (If that is the shape it will be).
It's a little hard for me to visualize the gun and "if" it will all work out. Starting with a 50mm square and going to oval, seems thin to me. I looked, but can't find it at the moment, for the dimensions with the taper.
