So I am lucky that I have an NFA H&R 410 handgun. With its 12” choked barrel, it shoots a nice pattern out to 25 yards and that’s with the 2 1/2” shells. It pattered better than the Pederosi Howdaw double barrel. Just wondering how effective the T/C is with its anti twist adapter on the end for 410 use? And will it accept 3” shells? Thanks.
