Recoil not bad (and I only weigh 170 pounds)I'm sure its heavier than the 20ga. I have lined it up for federal slugs, have also used the hornady slugs. Federals shot real good, actualy so did the hornady but they are hard to find in my area. If you get the 12 gauge the scope base is different it is a six hole and longer. I had to use tall rings so my 50 mm lense did not hi the base. The 20 gauge uses the same base as the rifle barrels. No signs of stock damage, I have fired a total of 72 rounds so far.
