my dad bought a used (few months old) Taurus Judge Polymer from a friend of mine that only put about 100-200 rounds through it. today we shot it for the first time since he owned it. shot fine first couple of rounds, when we opened a new box of the .410 shells, started loading up, all but one shell fit normal. the one that didn't fit, it would have had to be forced into the cylinder (which we didn't force it), we tried another shell and same thing would not go in smoothly without forcing it. took all the shells out and put new ones in and now only a few fit in and a few wont slide in with ease. could this be a defective box of ammo or is something up with the cylinder? no problems like this with the .45; shoots fine btw.
