I just joined the fourm and found this site on the Bruno's. My wife and I have a Bruno that we have had for almost 45 years and this is the first time we have found any information on (her) rifle. It is a square bridge 7X57 that was made in 1951. At one time it had a side mount for a scope. I put a weaver 4X on it in about 1968. I used a shim under the clamp for the weaver rings, and it has not moved in that amount of time. We used to call the rifle " the butcher", for anything we shot at died! Made two of the longest shots at game in my life with this rifle, well over a thousand yards at a couple buck mule deer. One does some unusal things when you are young and dumb. It's a 23 inch barrel, with a small schnoble forend, double set triggers, and spoon bolt. It has had the safety replaced this last year, for the original safety would let the bolt come open while carrying it over the sholder with a sling. It would then eject the round out on the ground. Must have lost several boxes of rounds over the years. I replaced it with a Vorere (I think that's the name) safety that locks the bolt. It's a really neat little rifle that will be passed on to our son. Best regards, Oldhunter.
