Re: Squib in my Ruger Blackhawk
Duds are easy to remove. I use, as you mention, a wooden dowel, on pistols. Rifles, I use a steel rod, capped with a cartridge case. Quarter inch with a 25 ACP case for up to 35 caliber. 3/8 with a 40 Smith for 41s and above. The brass cartridge case prevents the tip of the steel rod from damaging the rifling. And with rifle length, especially with a quarter-inch dowel, you get flexing and breaking, with wood.
But anyway, yes, you just tap it out from the muzzle, same as if you were slugging the barrel.
