Since it's been raining for the last week or so I started looking over my "dope" for the last 4 years shooting one of my rifles. I have been recording weather as well as "come-ups" everytime I shoot the rifle (25 days on the range with this rifle) over the last 4 years. Round count is about 800. I rotate rifles everytime I go. I start with Strelok and that usually gets me on the steel and then I adjust to hit as close to center as possible. I record all data for that shooting period. I haven't changed loads except to replace bullets and powder as needed. Things are ok out to 400 yards but as I go out to 800 things start to get screwy. Wind is not a factor since I only shoot on calm days. Could temperature change POI this much at longer ranges? I have the data, I just haven't looked at it. I started with elevation as needed to hit the target. It's a bit confusing but for example at 600 yards I dialed up 3.4 mils (200 yard zero) to hit center on 3 different days. Then, on three other days I dialed up 3.2 mils to hit center. Then, on 3 other days I had to dial 3.8 to hit center. I guess that is why they have "sighters" before matches? It's kind of tough to make a dope card when you have this much variation at long range.
6.5 Creed with 140 grain Berger VLD. Actually data in MILS.
This is not data generated from Strelok or other apps.
Values are for specific days with hits on target. 200 yard zero.
