I am working on a SxS now. It is a Simson Suhl with 25ТТ cylinder bore barrels. Plan is to work up a load (hopefully shoots well enough at 40-50 yards with factory loads) for hogs here in Florida., So everything is hypothetical at this point. Just another stupid idea that I dreamed up. I have been reading a lot of posts on different sites and it seems that good European double seem to regulate pretty good at the range I am hoping for, but they use Brennke slugs. Time (and a few slugs) will tell if I screwed up a good double by removing the chokes.
