We have three of the 4 inch models in my group and all of us love them! It is very surprising how accurate they are, and it never fails to put a smile on the face of anyone that shoots it! you can feel the raw power in the recoil. my wife knows how to hold a revolver, and she can put a full cylinder into a small paper plate at 15 yards all day long. Does it have alot of recoil. yes, but with that comes alot of knock down power. i think you will find that it is very managable.
we have two loads that we have played with. one is the 500 grain xtp, and the other is the 350 grain xtp. Its been awhile since we loaded up any 500 grainers, so i cannot recall the exact load data.
but we just loaded up some 350 xtps, and some berry 350 grainers for practice. They are 38.99 for 150 of them, and can be loaded similar for practice. we still practice alot with what we carry, but these others are nice for when someone comes over and wants to shoot it.
anyway, we use the starline brass and it has worked very well. we use cci 250 primers, and H-110 for powder. we load them up around 40 grains. Check the manual, or online on hodgdons website. i believe the start load is 39 grains, but double check to be certain.
