I have one in 12 gauge also.
Accuracy is great, under 2" at 50 yards .
I use Federal Premium 2 3/4" solid copper 3/4 oz Barnes Expander slugs @1900 FPS. Total devestation on whitetail deer with rifle like trajectory out past 100 yards.
Note on recoil: It's pretty fierce. I replaced my wood stock with a Virgin Valley Kevlar stock. The total weight is now under 6 pounds. After about 8 rounds of target practice from the bench, recoil flinch can become a factor if you're not used to it. I have a greenish/yellow bruise mark on my shoulder to show for 15 rounds fired last week.
If you're sensitive to recoil, you may want to try a 20 gauge.
