This may be the wrong place to ask but here goes. Has anyone had an issue with the case splitting midway between the shoulder and the rim? The split was about 5/8" long on 4 cases out of 12 that were shot, did not try the last 8 in the box, I am thinking they said it was 140 gn. new ammo, The POI was all over a 2" group at 100 yds. Changed to some hand loads with no problems.
