Sure just rub it in.. I missed the deal on the apex [:@].

Stick with pyrodex. start out with 80 grains pyrodex RS and the powerbelt, fire one shot at 25 yards to see where its at, adjust sights. winchester says u need to be atleast 2" high at 40 yards to be close to dead on at 100 yards. Once you work out to 100 yards, up your charge to 100 grains RS and see how it does.
This is my load:
Winchester x-150, 120 grains pyrodex RS, 245 grain hollow point powerbelt, sighted 2" high at 100 and dead on at 150 yards. And also, use loose powder so you can make small powder adjustments for tuning.
