Whitworth is correct, 100%. Accuracy first. We don't shoot much over 100 yards and closer, MUCH closer is better.
But a good revolver load should always be accurate. 1/2" at 50 is a good goal but 1" is great.
Here is a revolver group at 200 yards that measures 1-5/16".
IHMSA shooters will tell the truth.
