Mathsr,


Notice the sift in POI between your two circled 5 rounds groups? It doesn't matter how close together the first five are if those five shift on the target (which they will). If you continued to fire five round groups you can take it to the bank that a 2+/- inch group will appear where those ten rounds groups are now.


To put another way- it looks like the circled five are a bit less than an inch? If you hung a target as big as those five, would you hit it every single time?

The rifle is a Rock River Arms lower with a Mega Billet side charging upper. It has a Daniel Defense 16" LW barrel with a 7 inch twist. I have a Leupold VX-3 3.5X10 scope on it using Burris PEPR mounts. The forarm is rifle length made by Troy.

This rifle usually has the first three shots touching or nearly touching. The next two usually make a 5 shot group that measures between .5 and .6 inches. I've never shot it for a 10 shot group before and wasn't surprised when it opened up to around two inches. I don't know if the problem is the barrel getting hot because it is really light weight or not, but I suspect that it might be mostly the shooter losing concentration.



The average group size is 2.02 inches. I'm not surprised or disappointed. I'm also not going to change anything because I look at like the danger zone with this rifle increases as the barrel warms up. I circled the first five shots of each group just to see what happened to the rest of the string as I shot.


Range and Daisy the wonder dog.
