Has anyone had positive results in tweaking these guns to make them more accurate? There are popular tricks out there to help a Ruger no 1 shoot better, for example.

The trigger pull is already good.

Thanks

Is it not accurate?

I went to Harbor Freight and bought a box of copper O rings. Found one that fit on the forend and my groups improved.

Perfect. Do you have a measurement or product number for the o rings?

The inside diameter needed is 3/8 inch.
