As you know from my recent posts I just got my Ultra Slug Hunter Deluxe. I finally got to go to the range with it today. I had 4 boxes of shells - 2 boxes of Federal 3" Premium Vital-Shok Barnes Expander (1900fps, 5/8 oz) , 1 box of Remington 2-3/4" Premier Core-Lokt Ultra (1900 fps, 260 grain) and 1 box of Winchester 2-3/4" BRI Sabot Slugs (1400 fps, 5/8 oz). My game plan was to shoot the Winchester loads from 25 yards to do the initial setting of my scope. Then move out to 50 and shoot the Federal and Remington loads and do some final tweaking of my scope. Then shoot 100 yards with the Federal and Remington loads.
My first 2 shots out of the gate (Winchester loads mentioned above) were 1-3/4" right and 3-1/2" low and 3/4" right and 3-3/4" low. I adjusted my scope up 4" and to the left 1-1/5". Next 3 shots hit the bullseye as can be seen by the image below.

I then moved my target out to 50 and took 2 shots with the Federal loads and 2 shots with the Remington. The 2nd and 3rd shots from the top on the following target were the Federal loads, and the bottom 2 were the Remington loads. The top most shot was a final verification shot from 50 yards I took using the Federal loads after shooting from 100 and making a slight tweak to my scope to move the point of impact up a little at 50 yards.

The following shots were from 100 with the Federal loads. I believe I flinched slightly on the leftmost shot. (BTW - the Remington shots from 100 were spread out a little more - 3.5" left/.5" high, .25" right/4.75" low, and 4" right/1" high)

How do these shot groups look to the experts? The 25 and 50 look pretty decent. The 100 could probably improve with a different load and maybe putting the rubber o-ring under the forearm.
