I have been shooting five shot groups with my new 260 build and have noticed two touching then three touching, although still sub MOA. I have weaver style rings mounted on a EGW 20 MOA rail which is picatinny, do you think the difference in tolerances is the noticable diffrence in these flyers? I am changing to a 30mm tube soon and not sure if it is worthwhile to buy a set of temporary 1" picatinny rings that will sit in a box sometime down the road.Currently shooting a Leopold Vari-X III tactical and everything is tight.
