No problem. As you know, if you're shooting too far to the left, you adjust your rear sight (your eye) to the right. If you're are shooting high, you adjust your rear sight (your eye again) down.
The Brownies, we were talking about come from Browning with a straight stock ( no cast on or off), and the drop is fixed.
Now this is where it can get tricky. Depending on your ckeek bone (neck, chest, and shoulder), if you raise your rear sight ( your eye), your group/pattern will move up and may/will move to the right. If you lower your rear sight (your eye) the group/pattern will move lower and will/maybe move to the left.
This is where the Adjustable Comb (AC) comes in to play. You can change the "Cast" (windage) of the stock without changing the "Drop" (Elevation).
Most OEM have models with AC stocks, usually run about $200.00 to $400.00 above their basic model. Aftermarket stocks from the OEM will run about $500.00 to $800.00. You can ship the stock out to some guy with a bandsaw, and hope for the "best" for $300.00 to $500.00 plus parts.
A lace-on will raise the eye, and the group/pattern.
The pattern board is your friend, use the Dam thing!!!
