[QUOTE="brentc, post: 988725, member: 16938"] I found a load in a 300 Win Mag with 215 Bergers and H1000 with CCI250s that strung horizontally at 200 yards while running a seating depth test. The group was under .5 MOA, but as was described, there were two impacts almost right on top of each other, but one was .75 - 1 inch right of the first two. I couldn't attribute the group to environmentals or shooting form because it only manifested itself with this particular seating depth while developng the load under the same conditions. I treated it the same as I treat any load with a flyer. I knew something wasn't quite right with the combo, so I ran a primer test switching to the Fed 215M from the CCI 250 keeping the same seating depth, but dropped the powder charge a half grain and worked back up firing 3 shot groups. At .3 grains less than the original CCI 250 load, the horizontal stringing was gone and I was left with a nice .25 MOA clover leaf shaped group at 200 yards. I have since verified the load at several distances with positive results. The point here is that flyers can happen on the horizontal axis and just like any flyer, they can an indicate of an out of tune load. [/QUOTE]
