Just saw thius post and thought I would link him....you did a wonderful job of that.
As far as a 280AI done RIGHT....send it to Kirby,,,,I could not be happier. I have a fireforming target that I have not posted yet and will add it now.
Now to be fair to my formed loads, I have only shot the one group that SS7mm linked to on "the results"
Hope to shoot tomorrow at 300yds. Need to check the weather....WIND!!
If you have more questions about the 280AI shoot em at us. I have owned 3 of them but the other 2 were Encores.
