I have two that seem to beat out the rest at present. One is a custom Caspian framed 1911 in .38 Super, and the other is a stock Ruger Security Six .357 4" barrel. Both will do darn near 1" groups at 25 yards. Usually, I am two hands over a sandbags when testing loads, but not Ransom rested, etc, so both guns could be more accurate. I have many pistols that shoot well; some are harder to be consistentent with, though. These two make it easy. What do the rest of you have that beats out the rest?
