After seeing Nitro450exp's Lanber O/U 12 gauge rifle I had to have one.

So the first range testing with the Lyman 525 (510gr) shows some promise. The two groups are vertical and 6 1/2 inch spread. I'm looking for some insight as to bring the two groups together.

I was shooting at 25 yards and using no rest, offhand.

My load is 25 grains Herco, a Winchester 12AA wad, Remington Gun Club case, Federal 209 primers.

And the Lyman 12 gauge sabot slug.

I want bring the two groups together at 50 yards. This will be just right for Michigan hunting.
