I bought this R1 .20 cal rifle from Bob's gun and tackle in norfolk, va.many years ago. Late 70's early 80's. It was and still is a very accurate rifle. I had never tested the gun on a chronograph till today. It is shooting old silver jets at 787, wondering if this is on par compared to when it was new.. hoping someone here will advise with some shooting data of their own. Second what new pellet on the market will compare to the silver jets. My rifle loves them. Thanks Barry
