In the picture below, the group labeled "3" is from the OCW I did a couple weeks ago. The charge 0.4gr above and below it was a nearly identical group and barely any POI change so I went with it. I loaded some more and shot it last weekend and got 3 shot groups around 1.5moa. I loaded some more today and shot 5 round groups(the two groups you see on the paper bag) that are over 2moa.
I shot the ocw prone, both other times I shot from a bench. Both times using the same sandbags, weather was identical, and all the components came from the same package as the OCW rounds. I cleaned the rifle before shooting today, but I shot a few rounds to get it warm and dirty before the groups.
Then to top it all off last thing today I shot a group from my go-to factory match ammo and it grouped right under 1moa like it always does. ie. my shooting hasn't changed and the gun hasn't changed.
Why this huge change with my own ammo? I've used the same components since day 1. Even the brass is all from a single lot of factory match ammo and it was all once fired in my gun before I reloaded it. Primers, bullets, and powder are all from the same container.
I asked after last week and some said there is that big of a difference between prone and bench shooting, but I don't believe that - I shoot the factory match ammo the same regardless of my shooting position.
I tried reloading to get a lot of consistent ammo, the OCW worked great but I can't duplicate the performance I got on that day. What gives?
