boxbirder,

You are getting good advice. The gun is a shooter with lower pressure loads. Take a look at what you will get at wally world:



While this gun was meant to have a working service pressure that is much lower:



Those loads you shot as kid... They were loaded to provide enough pressure to operate a semi-auto.

There are alot of options for ammunition with pressure more in line to this gun. GameBore and RST come to mind. I know there are more. You can get a lot more enjoyment and less recoil.

I hope you post pictures of before and after if you decide to restock this gun.
