    Thanks, Dinny

      For a reasonably priced and user friendly chronograph, I like the Magnetospeed a lot.

      But I am convinced, when in use, it changes the barrel harmonics.

      And I have no doubt it changes the POI.

      Therefore, I use it only to determine velocity for load work up.

      I don't try for serious groups with the MagSpeed installed.

      And, switching pills in the middle of a session definitely changes things.

        I don't clean the barrel until accuracy starts to change from fouling. Then I'll clean the barrel, I don't clean after every session. Unless Iv used it in the rain, snow you get the point.

        Been a fan of the Grendel from the very beginning and haven't second guessed that choice one time.

          Not trying to be a Butthole but what does this have to do with the OP??

            I have the 22 inch Howa that shots one inch groups easily of bags, but changing from most loads to 120 gr Nosler BT will shift the group to the left nearly 3 inches. Different base, different jacket material? Who knows?
