[QUOTE="yorke-1, post: 2577582, member: 11960"] It's time for an update on the 161 Haymaker in a 300 Blackout. My work schedule has been a bit erratic lately, so it took me a lot longer than I expected to complete another round of testing. The groups in the pictures don't have any real significance since they're shot with a Magneto Speed strapped to the gun. The rifle is an unmodified Ruger American Scout with the factory stock making contact with the barrel on one side, and a spare scope that I found in the parts drawer. I use the groups to give a relative comparison between loads and to make it easier for me to catalog the data I record. I focused on Ramshot Enforcer this trip since it showed the most promise last time. [B]All groups were shot at 170 yards[/B].
