did it fly of or just form a crack? that certainly looks interesting

Just formed crack.

I have a crack similar like that on one of my big cannons, its not that deep and its just around the chamber.

I question if it is a crack or not, but once i get a recoils system with more upgrades to my 4SPC, then i wont be worried. And my dad didnt think it was a crack either, but it still seems abnormal.

liki: fill your chamber a little and add soapy water, if there is one tiny leak you will notice

When using high pressures in square chambers, they'll soon get a cylindric shape anyways. 8)
