[QUOTE="Greyfox, post: 852680, member: 10291"] A couple of questions. With 1400 rounds through the rifle, did the ES issues develop recently? If results were originally OK, did you change any components, or use a new lot of powder, bullets, or brass? Generally, you shouldn't see much, if any change with only a few thousandths of wear, particularly with standard shaped bullets. It doesn't seem like this should be your issue, but barrels can wear out prematurely. 1400 rounds isn't a lot for a 260, bit I had a 308 go bad at 2000 rounds which was not typical. The Magnetospeed can change accuracy, POI, or both. Some rifles are unaffected at all. It depends on your specific barrel's harmonics when the MS is attached to the barrel. It is critical that the barrel straps are secure and the unit does not move at all when fired. Using a piece of rubber, or the additional rubber pad on top of the barrel, under the strap secures it well. I don't measure groups, or zero when using the MS. Even with this inconvenience, I still think it's a superb unit for accurately measuring velocity and ES.IMO [/QUOTE]
