Posting this for those here who are thinking about trying a MD (also known as 'tuners') to improve accuracy of POI on rifles.
This post (linked) and the included 5 min. movie are the work of world-renowned custom rimfire gun builder, Bill Calfee, of Borden, Indiana.
The sole purpose of a muzzle device, is to move the 'dead spot' in the barrel's oscillation upon firing.... to the crown of the muzzle. Bill has made a third movie and will post a fourth, soon. I just wanted to help you understand the barrel's vibration (from ignition) and how to eliminate it's affect on the bullet... thus improving accuracy in your rifle.
Here's the link to Bill's post over at World Wide Accuracy forum, for "barrel ringing movie #2. To see what the theory of MD's is, just click on the still pic below where it says 'The Movie' in his post. Enjoy!
