Pops, I agree with everyone about the importance ...
of cheek weld.
There is an easy fix to your problem depending on the type of stock on your rifle.
The fix is the same regardless of stock: raise the height of your comb on the stock. It is very easy to do on a standard stock. They make kits which consist of foam pads of different thickness and a nylon wrap that goes around the stock to hold them in place. I bought one from Cabela's and used it to raise the height of the comb on a shotgun that wasn't patterning the way I wanted.
If your rifle has a collapsible stock I am guessing you could do the same thing with the right thickness foam pad and duct tape or electrical tape.
