1 to 2 ingroupsat 100 yds with a auto or any gun isvery good in my book. like you said forprofessional paper puntchers it would be sub par. i just shoot deer and have a very good kill rate
Depending on your hunting conditions,1-1/2" to 2" groups at 100 yards might be quite satisfactory,however that 2" group at 100 yards will become a 6" group at 300 yards and an 8" group at 400 yards.In other words,at those distances the rifle is barely capable of keeping all shots in the kill zone without allowing for any shooter error or windage error.On the other hand a 1" group at 100 yards becomes a 4" group at 400 yards which does allow for some shooting error or windage error while still keeping all shots in the kill zone.A 1/2" group at 100 yards becomes a 2" group at 400 yards which allows for even more error while still keeping all bullets in the kill zone.Accuracy has advantages for hunters,not just paper punchers.
