I bought a 77/50 that had been converted, couldn't get it to shoot consistently so changed it back and now have a flawless shooting inline black powder rifle now...I may have done something wrong but I just could not get it to shoot well with the 209's no matter what powder I used...not trying to persuade anybody, but Ruger did a good job when they made my 77/50 and it is a shooter as it came from the factory...
