[QUOTE="Just an Old Cowboy, post: 1761547, member: 109611"] Over the years, I've had a number of customers bring their rifles into the shop complaining about poi shift after the first round. It can sometimes be caused by a pressure point in the barrel channel causing a shift as the barrel heats and expands. Another potential area is improper bedding which again causes pressure points because of heat expansion when fired. The third thing I find that causes this problem is stress in the barrel and action from cutting and machining, most particularly in factory rifles. I've sent a number of these to 300 Below for cryrogenic treating, and had excellent results in either eliminating, or greatly reducing poi shift, and in many cases accuracy has also been improved, as a result of relieving these stresses, and the cost of this process is relatively inexpensive for the result. Hope this helps give a little insight of a few areas to start looking to resolve your issues. One or a combination of these three things will almost always resolve this problem. [/QUOTE]
