Not really disagreeing. But bench shooting is not necessary an indication of field shooting ability. I guess the only point I'm trying to make is that small increments in rifle groups are not significant. What is significant is the small groups obtained by the shooter in the field.
As Father Frog has so aptly pointed out "If you can't do it with a 2 minute rifle, you can't so it with anything.
For a thoughtful discussion of this topic go to Fr. Frog's websight and read quesition # 5 in Miscellaneous- "Will a more accurate rifle make me a better shot".
