I didnt see the smokeless sub forum so I guess it got nixed. Anyway I had a h&r 4570 converted by someone off of Doug's message board back in 2014 so 8 years ago. I can not remember which breech plug he used. It has a tungsten core bushing in the center and a Allen set screen on the outside to hold the bushing in. I am not having any trouble out of it but thought I'd go ahead and replace the bushing before season gets here. Problem is, I can't get the bushing out and I don't know where to get one. Any info?

I wouldn't worry about it, tungsten bushings are designed to last hundreds of shots maybe thousands the only reason to replace it is if it splits into, or cracks which does happen sometimes because they are so brittle.
