JH45, I shoot the Sk Standard Plus in my Sako Finnfire and find it to be very accurate in the Sako. Also have one of Clark's Custom Ruger 77/22 that I shoot this ammo in. I shoot rifle silhouette and find this to be an outstanding ammo for $ 2.00 per box. Both my guns shoot the Sk under 1.00 @ 100 meters. On a calm day the Sako Finnfire will shoot about 5/8" at 100 meters. I never group my rifles at 50 yards like most folks, because the real test for 22 rimfire ammo is at 100 meters. Almost any ammo will shoot half an inch at 50 yards with a good gun and scope, but 100 meters will separate the good stuff from all the rest. Occasionally I will get a flyer that opens up my group to about an inch, but this is more accurate than I can shoot my rifle offhand most of the time.
I've shot lots of Eley Tennex and other expensive brands that cost upwards to $ 10.00 / box. But SK and Wolf will shoot almost as good and they are made by the makers of Lapua..... These ammos are an excellent buy. I bought 2 cases of the SK Standard plus and this is my main ammo. I have several different brands but the SK is what I shoot in the matches.........Don
