I have a good load with 180 gr TSX @ 3.620 oal. I wanted to utilize some 200Gr. Barnes LRX and seated @ 3.645. I was lucky to have a hit the paper. 8" high and to the right. Next shot was 8" high to the left and my 3rd shot was 2" low. I was dumbfounded. Checked everything to make sure I had nothing loose anywhere and Shot some of my 180 gr TSX's. 3 shots and they were all touching. Only thing I can come up with is that the LRX are tipped and I need to seat them further out. I can go 3.815 and magazine works as well as dumping a unspent round. Should I start that long and work back or pick a point and work up to that length? Still not near the lands.
