Wish I had seen this thread earlier.
I just spend $35 on a cylinder loader from S&S Firearms. It's junk.
Any of these loaders that swing the ram on an arc will not seat bullets squarely into the cylinder. There is no provision for adjusting the position of the cylinder, either, so my ram doesn't even start off square.
I'm liking the Black Dawge loader mentioned above. It has adjustments for the cylinder position and the ram moves on a straight line.
