If you have a gun that's regulated, what are the ways to increase power? I know turning up the regulator will increase power. What about increasing the tension on the hammer spring? Since the gun is regulated, would that still increase power or not? Would one both increased the regulated pressure and the tension on the hammer spring? The reason I'm asking is because I want to get a .25 rifle that will shoot both the king heavies and the regular kings. I thought of the Royale 500 with the power wheel adjustments, shooting the heavies on high and the regular kings on medium, but the power would have to be turned up. So, how to do it? Also, would I be better off getting this rifle unregulated? Would that make power adjustments easier? Any input on this would be appreciated.
