I agree, if your keeping 10 shots in 1 inch at 100 thats plenty good, then 10 shots in 2 inch at 300, thats definately suitable for anyone.
oh sure there's some benchrest shooters i know of that wouldn't be happy, but these particular guys are..um...shall we say, anal-retentive about anything more than 1/4 inch 5 shot strings at 100.
so unless your looking at building a longrange benchrest rifle, i think you gotter whipped.
