I do not think that leading is an issue, they have cleaners that take care of that. I think if you have a bore brush you will be fine. What twist rate is your gun? Those are good groups. Is the max charge you have at 110 grains based on a certain bullet weight? I think the posted max charges are all based on a certain bullet weight for your gun, if you go over that posted bullet weight back the charge down a bit and you should be fine, just saying.
