I tried it with my latest acquisition--Smith & Wesson 27-2 .357 magnum. I don't figure to carry this 48 oz N-frame, but it should see some nightstand duty. I thought I hit the line with the 2nd 10 yd shot, but when I got home I realized the 10 ring on the target I grabbed was quite a bit smaller than a 3 x 2 oval. It's close to 2 3/4" x 1 3/4". If you look at it against 2" on the ruler, the one on the left would be well in. So I'm calling it good. At any rate, I'll take a 1.43" 20 shot double action group any day.
