[QUOTE="ss7mm, post: 168095, member: 5"] Looks to me like the cold bore shot at only 100 yards is totally unpredictable and since the first shot counts maybe you should look at the 3 cold bore shots as a 3 shot group and adjust accordingly. The only problem with this is then your "group" average location will be off. Yes your 2nd. and 3rd. shots groups quite well but the first shot is the one that counts. If it was me I'd shoot for "groups" at 200 or 300 yards and zero based on the center of the group and then determine my maximum range from the results. I believe it's easier and far more accurate to determine your vertical and horizontal location and dispersion at longer ranges than it is at 100 yards. You can't reliably say that a 3" group at 100 yards will equal a 12" group at 400 yards as most guns tend to shoot slightly bigger groups as ranges increase. Have you shot it at 400 yards and if so what were your group sizes? Is this the best load for this gun or do you have time to do more load testing? [/QUOTE]
