I went shooting today since I got out of work early. Was around 60 F with 5 - 10 mph inconsistant wind and I was shooting 100yds off a bipod at a standard 100yd sighting target. This was my first real attempt with my new rifle and my first load that I made just to see how it shoots and break in the barrel. I don't know what is the proper procedure for measuring groupings so I'll tell you how I got my measurements and I'm sure someone will tell me if I'm doing it correctly or not. I wanted to find center to center hits so I measured the widest spread outside to outside using a digital caliper. I then subtracted the diameter of the bullet. Those are the numbers I'm going to be using as that is where I feel the bullet actually hits. I don't know if when people talk about groupings it is supposed to be the overall width. Anyways....
This is the whole target. 20 rds, four 5 shot groups with a quick clean after 10 shots.
This was the first group with the flyer being the cold bore shot. discounting the cold bore shot I measured .533"
this was the second group after a 5 min cool down. I measured a .471" center to center group.
This was after the barrel clean. Another cold bore flyer that was fairly consistant with the first. Discounting the cold bore shot I measured .397"
This was the last group after a 5 min cool down. I measured a .463" center to center.
This is the rifle I'm using. A Remington 700P with the barrel cut down to 22" with an AWC Thundertrap suppressor and a MK4 LRT scope.
