Over the weekend an acquaintance and I were discussing shotshell, factory and reloads, in handguns, primarily revolver. He mentioned that SPEER warns against shooting them in ANY ported barrel. Later he sent me copies of the SPEER manual citing those recommendations. His earlier SPEER manuals did not make any mention avoiding shooting them in ported barrels. SPEER claims it is possible for pieces of plastic and possibly even shot can be forced out the port causing a hazardous situation to shooters and bystanders.
THIS IS IN REFERENCE TO SHOT CAPSULE TYPE SHOTSHELLS FOR HANDGUNS!!
In a way, this reminds me of the "no cast bullets" in an M1 Carbine myth, because it will plug the port and piston, which has pretty much been refuted by thousands of shooters.
If this is true, how is it that one can shoot ported shotgun barrels? I realize the shotgun port is quite far forward so the shooter is probably OK, but bystanders would still be at risk. Also, most handgun ports are oriented up, whereas many of the shotgun ported barrels have multiple holes located on top and SIDES of the barrel.
I don't own any ported handguns so I can't do any testing but I suspect it is a case of CYA by SPEER in case some idiot does something stupid and tries to blame it on the port/shotcapsule combination.
What are you feelings about this?
