Question regarding Hevi-shot and H.S. Strut Undertaker
I noticed that HS Strut makes a choke tube specifically designed for Hevi-shot (HS Strut HS Undertaker) which has a .675 constriction. I currently own the regular HS Strut Undertaker choke tube which has a .665 restriction. Can I shoot Hevi-shot through this choke tube safely or do I have to get the .675 restriction model?
If I do, will it harm the barrel or action?
Has anyone shot Hevi-shot through either of these choke tubes and what kind of patterns did it deliver?
