Well spent another morning on the range and this time I used only cast balls that I had cast sorted and weighed. Kept them all within .5 grain range. Used the same load of 15 grains Swiss, .010 patched lubed with Hoppes BP Lube. Shots were from 20 to 40 yards from a bench resting on a back pack. I also only shot one gun today and ran a spit patch between shots. All 40 shots stayed within a 1.5 inch circle most being within 1 inch of dead center. I did manage to load with no powder for the first time also but was able to trickle enough powder under the nipple to fire it out. Again nothing earth shattering but enough to decide I dont need to be be buying swaged balls when I have molds and 60 lbs of pure lead to work with. Doing all of this to get comfortable with this gun to start squirrel hunting. At the end of the day I guess if you have what you need to cast your own there is no reason not to but if you want to buy swaged they are alright too. Whichever you do weigh and visually inspect the balls for best performance.
