Regulating the regular light barreled double shotguns with our faster slug loads, using larger amounts of slower powders, does not work. They have to be loaded slow like shot loads.That's why Rob is mono-blocking in heavy thick barrels on one, in the 12ga FH caliber to get the effect of acting like a heavy barreled double rifle.He should be done this winter. If I do any it will be a heavy barrel o/u 10ga, if I can get one in the future I saw that was heavy enough.Ed
