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.

Ruler on the group. It isn't what the group was measured with initially, but it is as good as I can do from the house. Did I forget anything else? I'm trying my best to lock down last place and want to be sure I get it right! smile
