You seem knowledgeable. Please take a look at my post #22. Thx.
For the price of a new custom stock, you can step into a new rifle.
Other than that have you tried turning the rear portion of your scope outward? This increases the length of the scope and reduces the eye relief distance. Cutting down the stock to a shorter length might be an option also. Check with a local gunsmith as this could be your most affordable option.
I priced new stocks before buying a new rifle. I was thinking I could upgrade my back up rifle with a new stock ... better bedding free floating barrel etc. But at $300 plus for just a stock I couldn’t justify it.
Have someone more knowledgeable than you remount your scope and see how that works. Not a ding on your knowledge, I’ve been shooting and re-loading for decades but my neighbor mounted my new scope and helped with load development ... he knows what he is doing and gets paid for it. I would never have the accuracy I have now without his help.
Good luck!
