From photos and notes in UJ's Sheridan book, it appears the hole was added in 1951. That's a dandy piece of walnut on the stock!Don R.
It was already enjoyed for 75 years-LOL….Enjoy that classic. Its hard to beat and Americas best airgun in my opinion.
Dud you put a little oil on the cup ? I would add a few more drops, & shoot it several times with 8 pumps, & check the results.
I have never seen one shoot 800 fps , even with the lighter pellets, unless it has been beefed up.
