Anyone else ever have this happen ? working up a load for my 338 lapua, have a load for 185 gr barnes and 225 gr barnes. Going on a bear hunt with the possibility of 300 + yd. shot so I thought I would work up a load of 265 barnes LRX. Went to the range fri. eve. the 265 were all over the paper, this gun usually groups under an inch! Tried some 185 and they were all over! Next tried 225 and they were all over! Checked the mount screws and the screws for the stock, both were tight.Appeared as if it was shooting to the left so I thought I would change it, upon removing the caps I found the screws for the turrets were loose! They were ready to fall off ! I tightened them and the next three cut each other, then shot my last two at 200 yds. they were about 3/4 inch apart. Never had that happen before ! Anyone else ever have this happen?
