I am a newbie to benchrest type shooting. I'm using a Sinclair Competition rest, a Protektor DR rear bag with 1/2" spacing, and a Savage BR stock (bottom of butt is flat and basically parallel to the forearm). Looking through the scope and running the rifle back and forth, the crosshairs always track down and right. The vertical I get... its a function of the stock being thicker as it nears the palm swell and that causes the the rifle to raise in the rear bag during recoil. I would imagine the yaw is bag alignment, but is that alignment of the rear bag to the front rest? The front bag doesn't sit straight? Rear bag not straight? I haven't yet found information that clearly defines the accepted methods for aligning the bags and troubleshooting tracking issues. Not being able to solve this on my own is making me feel rather dumb and I've considered my rifle might make a better lamp stand than what I am doing with it! Grrrr... And tips, pointers, methodologies etc would save my rifle from wearing a lampshade. Thanks all!
