Ruger #1 rifles are beautiful to look at, but can be somewhat frustrating at times. I have several, and if I could afford it, I'd have dozens more. I am willing to put up with their idiosyncrasies, because I love the challenge. I'll give you a few examples. I have a 7x57 1A. I had to send it back to the factory for a new barrel. The original barrel had an overlong throat. The 06 will do about 1 1/4 inch after the first shot which is 6 inches high. Go figure, I can't. That's a 1B. Another 1B in .300 Win. Mag does 3/8 inch with preferred reloads. The .375 H&H does about 2 inches, a 1A in .270 2 1/2 inches, the 45-70, 3 inches. All mine are early models. I believe the newer ones will do better. I don't know what standards for accuracy Ruger has for the #1's but the 7x57 will now do from 3/4 inch, to 1 1/4 inch depending on the load. With practice, you can shoot a #1 almost as fast as a bolt action. Just ask me if I love my #1"s. You bet I do.
