John, that is a a nice one and it doesn't get much earlier than that! What a great Parker! It looks to be all there. Are the barrels 30"?
As far as shooting goes I took it easy with mine knowing the age and barrel steel. The most recoil, which wasn't much, was out of the black powder shells 1oz and 2 1/2 drams.
I never felt like I was putting too much stress on the gun.
The RST 3/4 oz. shells didn't have hardly any recoil and performed well. I shot some of my ultra ultra light reloads, which are 5/8oz. and 14 grains of Red Dot(those pink/red shells in one of the pictures). Those were like shooting a .22 and I was still hitting targets.
The most fun of course was with the black powder shells. I think you could back off to a 20 gauge load of 7/8oz and 2 1/4 drams and still have some fun.
Oh and my daughter will give me the business at some stations if I can't figure out a target or miss a few. This video was just at a "good" station
