Cheek Weld

This is a key issue for field shooting. Some benchrest shooters would argue about cheek weld because they shoot insane groups with no cheek contact at all. That is fine on the bench but field positions are a huge difference from the bench.

The cheek rest portion of the stock should be parallel to the bore of the scope.

If it is not, if it drops in the front or rear, it is nearly impossible to get the same height to the scope by virtue of the fact that any given point on the cheek rest is a different height in relation to the scope. All it takes in conjunction with an angled cheekpiece to ruin a shot is a field condition or fitting issue that places the face in a slightly fore or aft location, thus changing the eye’s position with the scope.

If you keep these axes parallel, it helps to minimize some differences in shooting positions. I adjust cheek height by mounting the rifle with eyes closed, then opening them to see where I am at. When it is properly adjusted, I can close my eyes, mount the rifle from or in almost any position, and see the same sight picture when opening them. It is important to note that if you have to move your position or head even the slightest bit, that you are not properly adjusted. Ultimately, when properly fitted, you should be able to be in position for long periods of time without getting neck fatigue or being uncomfortable.

In the above photos you will see the difference in the angle from the eye to the scope. Even though there was a clear sight picture in both photos, quite clearly you’re not looking through the scope the same. All that is needed to correct this is to raise the cheekpiece for prone slightly and change our bench technique slightly so it is the same. Once you feel you have it correctly adjusted, go to the range and shoot from the bench, and follow those shots up with shots from prone to confirm there is not variation in point of impact.
