Because of the bullet length and dimension differences its rare t9 have a chamber freebore setup ideally for both 185 juggers and the 215s. They need vastly different freebore lengths to have them seated in the neck properly. The 185s are also about the ideal bullet shape and weight for the 308W case.
Also when you change bullets never count the first shot even with a warmed up barrel. Many times that first shot using a different bullet especially a different powder will shoot off. So always shoot one fouler shot first. If you look at the last 3 shots of the 215s they are into about 75" which @ 300y is between ¼ - ⅓ moa. The 215s are always going to group lower until you get out past 600 yds. You shoot 215s for wind 9n fixed known distance shooting. Assuming this is for for. Also you need more rigid support for the target. With that head/tailwind it's moving the target enough for a 1"+ on the group poi/poa variation.

Juggs are awesome, easy to deal with
