Hi fellow gun builders and spearos, I need your advice on safe barrel dimensions for my next project.
I have gotten my hands on a 7 mm/140 cm spear and need a gun to go with it.
I want a 2 band gun, 16 or 18 mm bands. I'm building the gun out of teak lams.
I want a slim gun that tracks easily horizontally, so i'm thinking of a Riffe style barrel but more rounded.
I wouldn't want to build a barrel only to find out that it bends under load.
How slim can i go without sacrificing rigidity?
Please
/Henrik
