I've seen MANY MANY Smith Revolvers with tight chambers (mainly M18's) and in fact years ago (in the late 80's) guys who were in my shooting club back then had sent theirs into the Factory for the same reason. The Factory did exactly what we are doing and sent them back. It is not uncommon to still see guys scrubbing the charge holes with brushes to reload another cylinder full. Like I have stated above, I have never had this problem with any Colts I own and the same ammo is used.

I have experimented with different brands of ammo and Remington seems to be slightly better, but unfortunately the Remington ammo these days is real junk and I much prefer CCI and Federal.

That is why I caved in a while ago and did mine. I have noticed no change in accuracy, but at least I no longer need to struggle ejecting empties after 30 rounds!
