[QUOTE="VinceMule, post: 3071159, member: 122164"] Multiple three shot groups saves a lot of throat wear as the fourth and fifth shots really heat the barrel up, not to mention copper issues. The first three shot group is just getting started. If you get groups where the group is vertical, then add .2-.3g more powder, if they are horizontal, then adjust seating depth in .003 increments. Don't be surprised if you start shooting single bullet hole groups. [/QUOTE]
