check out the bedding and the floated barrel, my load is 55 grs imr 4350 with a 165 gr nosler BT bullet for 2700 fps. target 100 yards from a lead sled, lower two shots-next two shots after a adjustment and the next two(shots 5-6 after adjustment) started to open up. my luck it would be ugly tooth less witches and home made rotgut.
