Hey, well I bought my Wife a 243 77 the other day for Christmas, I bore sited it and test fired it christmas day, we had a warm day here in the arctic , 15F
100 yards, 2 shots hit the 16" box 5" away from the circle I drew on there. group 3" apart. the wind was blowing 10 mph. so Im glad it hit the box, will fine tune it later on at 200 yards without wind for dead center.
Im hoping it will do good.
