I just bought and received some 38 special wad cutter ammo and I am not to thrilled with it. Problem is when I chamber the ammo in my Rossi M-68 snub I can hardly get the cylinder to close and dang straight can't revolve the cylinder. The ammo is jammed tight against the backing plate. I notice I have to push the ammo in with my thumb to get them flush with the cylinder. Have to force the cylinder closed if I can even close it. Also I have to hit the ejector with something to eject the ammo. I tried some other reman ammo in the Rossi and have no problems with it. I have never had a problem with this Rossi jamming. I can't see any light between the plate and the casings with this ammo but other ammo I see the clearance just fine. I tried the ammo in my Rossi M-85 which is basically a clone of the M-68 except it is stainless instead of blued. The ammo fits this gun ok. I put this ammo in my GP100 MC and it also works fine and can see the clearance as it should be. No problem ejecting these either with this ammo. I am guessing the clearance on the M-68 is tighter but still other ammo works fine in it. What is the problem here? Looking at the casing at the primer end it is thicker than my other ammo is. That has to be part of the problem and I wonder could that be causing the hard to eject also? Why is the top ridge thicker on this ammo? I checked the ammo casings and found various brands Federal, R-P 38+p, G.F.L., OBC, R-P, Blazer, and they all are having same problems. I checked my other reman ammo that does work ok and it also has many of the same brand cases. Why are these no go cases thicker on end?
