Oh dang. Forgot to mention this one. Ruger M77 MKII, 308 Winchester. Initial load was 44.5gr varget with 150gr partition, loaded to book length 2.800”. This load shot 1.45”. I loaded the same load, but with the bullet .020” off the lands, and shot a sub .5” group. It doesn’t always happen like this, but it definitely goes to show how important seating depth is sometimes.
