On the bicycle I carry a Taurus Titanium .45LC since the ammo is the heaviest component on the lightweights. I don't carry factory ammo because I discovered that the Taurus is so light that when cooking off a couple factory rounds the recoil actually backs out the projectiles from the remaining rounds sufficiently to block the cylinder from rotating.
Thus all rounds are homemade, slightly less OAL, a much faster powder and a roll crimp. Problem solved.

I have seen this happen. And I have seen forcing cones crack or expand to the point that the cylinder will not rotate.

Years ago, we found that out on the range when I worked security details for a bank. A couple of our issued revolvers (Shows my age there that we carried revolvers, eh?) had forcing cones that would expand after a few rounds fired and the weapons would fail. Also, a buddy of mine broke a spring on a new Colt Python in his first 50 rounds with the gun.

Always make sure you've got enough rounds through your weapon that any manufacturing defects will show up before you need it for real.

when a revolver binds up like that, the weapon gets serious inspection for defects. Then when none were spotted, I went ahead and measured the OAL of the factory rounds in the cylinder comparing them to the remaining rounds in the box. The projectiles actually backed out of the cases. I'm pretty sure different grips would make a difference. Taurus was using those goofy soft grips then. The Titanium snub nose in .45LC is now a collectors item. Can't find them anywhere, probably just as well.
