The No. 1B has, as mentioned, a semi-beavertail forend and a 26" Medium Heavy barrel, and noiron sights. I think it is probably the most numerous model of the No.1 made. It is still very much a part of the Ruger No. 1 line. THERE ARE NO "FACTORY SECONDS" of ANYRuger firearm!

The very first Ruger No. 1 I ever got was a No 1B7mm Rem. Mag. (1969). This rifle shot 1", 5-shotgroups AT 200 YARDS right out of the box, (Leup. 2X-7X scope). It will launch 140-grain Nosler Partition bullets at 3350 FPS and Nosler Partition 175's at 3070 FPS., with half-MOA accuracy! I have not shot it very much (got a 1A in 7X57 because the 1B is so heavy!) and it still performs like this.

The 1A's and 1RSI's are sexier, but there's a certain "feel" you get when a 1B is in your hands-maybe it just has great balance, despite the weight.....
