I m shooting Moly-coated bullets and my groups are much larger than they were with non-coated bullets. What s the problem?
• It will take approximately 15-30 “fouling” shots with Moly-coated bullets to deposit a thin coat of Moly to the bore. The first coated bullet fired will deposit a small amount of Moly in the bore close to the throat. The next bullet will deposit more Moly where the first left off. Moly deposition will continue towards the muzzle until the entire length of the bore is coated. These fouling shots will provide a sporadic group because of the varying amount of friction in the bore. After the fouling procedure rounds should “settle in” and groups will tighten up. • Moly-coated bullets will reduce pressure and velocity. Loads need to be worked up slowly to attain original velocities. Dramatically reduced velocities generally deliver poor accuracy results. • It is suggested that loads be chronographed when working up a new load. It will be much easier attaining desirable results with velocity data from your firearm. This is true for all load testing, not just Moly loads. • Some non-Moly coa
