I have two 357 revolvers and I have shot them both before but never on paper, so today I went out in the sand pit to see what they would do They were both shot with two kinds of ammo in 6 shot groups at 25 yards standing, leaning over the bedrail of my truck for a brace (real scientific I know!!) there was a brezze blowing but not real bad. The Ruger service six 2 3/4" barrel would not do any better than a 12" group!!! and most were off the 8x11 target on to the box it was tacked to(high and left) My Smith&Wesson 65 4" barrel was better with consistant 4" groups real close to and on the bullseye. Both of these guns are stainless with fixed sights. I shot both 125g 357 and 158g 38sp in both guns. Is 4" groups the best I should expect? as a side note, with the same conditions my old Ruger mark1 22 with a 6" barrel shot 2 1/2" groups into the same target today as well, so the wind was not that strong. as another side note I think the service six is for sale!!!!
