Read a good article on barrel accuracy,and vibration,and how to make your gun more accurate. Thought i would pass it along to any and all whom would be interested. It answers a lot of questions and misconseptions on barrels. vangunsmith the sight is www.precisionshooting.com/psm_2005_03_issue.html Enjoy vangunsmith
Thanks for mentioning the article. Good ideas. We have been having great luck improving accuracy with using the Limbsaver Barrel De-Resonator. It is a simple Rubber collar that you slip over the barrel and changes the barrel vibrations to match you bullet. Simple but it reduces group size. Low cost too!
