You are fortunate just being clueless on conversion.

I am feeling pretty clueless on all of it. Think I got the gist of it.

I realize there are lots of places to get low pressure shells, but aren't they all in 65mm lengths occassionally 67mm. Do you know if I can shoot 65mm shells in a gun chambered 2 3/4" without long term ill effect?

Thanks for heads up on wall thickness for chamber area.
