I guess I have to add my $.02 in here. I also own an H&R Ultraslug in 12 ga. and it soulds like mine is rigged exactly the same as a couple of other guys on this forum. A 3x9 Nikon Slughunter scope with the BDC reticule and a Limbsaver recoil pad. I have only owned my Ultraslug for less than a year now but I've used it enough to know that it is the best shooting slug gun I've ever heard of. I took it to my local range shortly after I got it and sighted it in at 50 yds using Winchester Partitioned Gold sabot slugs on the dealer's recommendation. My first 3 round test grouping was at 50 yds. It was a single ragged hole. My next 3 shot group was at 100 yds using the 100 yd aimpoint on the Nikon Slughunter scope. Again a large single jagged hole . . . obliterating the bull! Then I moved to 150 yds using the 150 yd aimpoint on the Nikon Slughunter scope and shot a wide cloverleaf . . . but a cloverleaf . . . off just a hair at 1:00 o'clock but destroying abot 25% of the bull in that area. At 200 yds, the 3-shot group spread to 3 inches and seemed to drop to the 5:00 o'clock point but one slug was dead center bull with the other two no more than 3 inches away (measured center-to-center). Now admittedly, this was shooting from a sandbagged rest but I can't shoot this well with my 30-30 Winchester even from a sandbagged rest. I don't know if I got lucky and bought a 1 in a million Ultraslug or if most of them shoot really well but I do know this, the 12 ga. H&R Ultraslug is now my goto gun for deer hunting. It is a bit on the heavy side with the scope but since I only ever hunt from a treestand, it won't bother me. I never did try any other slugs as I am perfectly happy with the way the Partitioned Golds shoot out of my Ultraslug. Why mess with success. By the way, I hunted with my son who lives in rural Wisconsin this year and took three deer (all on the small side) with my Ultraslug . . . all were one shot kills and dropped where they stood . . . no tracking at all! My farthest shot was almost exactly 100 yds. That reminds me, get yourself a good rangefinder. They are worth their weight in gold if you are going to shoot any distance with slugs of any kind.
