I went shooting today and decided to check my zero on a Remington 700 w/ 1-9 twist Pac-Nor 3 groove. My load is 85 gr. of Reloader 25, Fed match primer, 162 A-max bullet .020 off the lands. Conditions were: Overcast with temps in the low 50's w/ 92% humidity.
First group 10 MOA high and 3" @ 100 yds.. This from last fall's 200 yard zero and 3/4 MOA or better groups.
Adjusted zero 8 MOA down and shot 3 more. 3" plus.
Started another group. 1st shot 6 MOA low. #2 OFF the target altogether! #3 was 2 FEET right and 1 foot low. Bullet tore a jagged hole in the paper.
This barrel has less than 100 rds. down the tube.
Bore scope shows excellent interior. Lands in great shape. Throat is fine. crown is fine. I can find nothing wrong with the rifle. Mark 4 seems to track fine. all bolts and screws torqued on scope and action.
Could this bullet be coming apart, because that is how it is acting. I find that hard to believe, so if anyone has thoughts, I'd like to hear them.
