Welcome to the best firearms forum on the web. The problem you describe is normal for Judges. Most 410's made for handguns will fit ok, unless ribbing is too aggressive. Tip: shooting 45LC prior to shooting 410 will cause seating/extraction issues. Because the carbon left in the cylinder after shooting 45LC will reduce cylinder diameter slightly. I always run a patch through the cylinders after shooting 45LC before I move onto 410. Also I try and keep my 410 loads below 1150 FPS, both for less recoil and wear on the Poly Judge frame. But not to worry there are lots of 410 bird loads that have 1150 or lower fps. Find the 410 shells that always seat easily and stick with that brand if the sticking concerns you. Another reason to not use hot 410 in a judge, is that the spent shell case will expand sometimes too much to get out. Have fun.
