Chronograph data thoughts???
First 3 shots were 3 to 5 minutes apart. Because they were identical I thought my chronograph might be bad so I put three in the mag and fired them very quickly followed by 3 more in the mag then quick for 3 more. Last one was a short break then 1 to fill out the 10 shot test.
Groups
1) 3 in virtually the same hole
2) 3 in .25" clover leaf
3) 3 same as above
Last shot was raining so hard I just let it rip through the center of the chronograph.
Results are below. I would love any thoughts or input. 1-3 seems too good to be true. It's a hunting rifle so first shot is most important.
