Thanks guys. It's nice to get informative,friendly responses. And Skunk,remember that Mauser I was trying to I.D. and I couldn't get the barrel band screw off my VZ-24? Well,I tried some more and finally had to give up before I made a real mess out of the screw head. But on a better note I did buy the rifle (just last night) and it's in .257 Roberts. The barrel has no markings other than 257 so the maker is a mystery also but I know the former owner so I know it's a Bob. Now all I need is brass and let the fun begin! Kix
