I think most of us are " what if I....". This hobby is kinda based on that thought line. We are always tinkering with loads, barrel lengths, optics or cartridge choice. There are so many ways to improve......or make worse any part of this.
I should have known if I thought of this someone else already had. I have a Dan Wesson and have always thought their barrel set up was really well thought out. Maybe the system would would to switch barrels like remage.
Since you are experiencing. How about machining the barrel down to allow a cf tube to seat at the camber end and thread the muzzle to accept a battle nut or brake to preload the tension on the barrel? Kinda like the Dan Wesson revolver.
Sorry to hear this Rum Man. I had my appendix rupture and tested positive for covid at the same time. A week later I was in the er with pneumonia, cobie and bacterial infection. I spent 8 days in the hospital and still trying to get my strength back. I will have a drink for you and keep you in...
