I own a Fabarm 9.3x74R. I have owned it for about six months and have put approximately 250 round through it with out any trouble with the single trigger doubling, or any other problem. Most of the rounds fired were during the regulation process with various bullets. Fabarm garantees that they will group the regulated load (which is 293 grain RWS Factory ammo) into 50mm at 50 metres.
I bought it from Tim at Mcdonalds Guns in Footscray. I am having a selector switch put in by Tim, to allow me to select barrel. This is mainly so that I can wear the barrel evenly as when hunting the first barrel tends to be fired more often than the second. This rifle is also used in competition. (I am aware of a winchester double in this calibre that is worn in the first barrel that there is signs of the bullets key holing. About 8000 round through that rifle.
My regulated load is with the 286 grain woodleigh at 2300 fps. The best 2 shot group I have achieved at 100 yards is 1 3/8" and regularly places 4 shots into 2 1/2" at 100 yards. I have not blooded it yet, even though it has been on a couple of sambar trips around Jamieson.
