I have a problem with my finished roll crimp. It is almost always crushed to the outside of the hull on one side. It fits the chambers of my guns okay and doesn't affect the pattern but I'd like to make it better. I use a early 1900's hand crimp and I've tried all different techniques for crimping from, using light pressure, light to heavy pressure, heavy pressure, etc. I've checked the head of the tool and it seems fine. I have a couple of these tools and they all do the same.

I've used all types of hulls from Winchester, Remington, Federal, Fiocchi, and others. Some have low wall brass and some are high wall.
Hulls are 3" cut to 2.5" and the lip shaved a bit to thin the wall so the roll forms better. I use BP then a lubed fiber wad, a shot cup, shot and over shot card.

Just not sure what I'm doing wrong.
