Chuck, I'd really like to see you try that but, I would think you should test it without porting, and then port the barrel for testing, even in varying degrees, testing loads in it all along the way. Might learn even more by doing this. I will donate a 12 ga. Rem. 1100 barrel for the testing.

Don, let me chew on this some today while I harrow some firebreaks in the pine plantations. I'll get back to you tonight. Thanks for replying.
