Hey guys, just got another question on this topic so I hope I'm not hijacking the original post. O brought a set of 13, 14, and 15 pound hammer springs from wolf and an Eric grauffel firing pin, the concern I have is that the length of the springs. Out of the three the 13 is the longest with the 15 the next longest and lastly the 14 the shortest. Is this correct or have wolf mixed them up putting them in the packaging?
