Just bought some for defense load. It is costly for sure but seems like an interesting idea. Thought I would give it a try. I have used the 165gr.+P .45 CORBON for awhile in this role and have never had a problem in my G30. Runs it like a champ!
If I can get around to doing some GEL tests(which I have yet to try...EVER) I will but we all know how that goes.......
