[QUOTE="556, post: 926615, member: 78030"] I have the same problem with my sons Ruger M77 MKII 257 Roberts. No matter what load I try I am always 150 - 250 FPS slow with majority of the loads are closer to 250 FPS slower. My barrel is a 22" barrel; 2" shorter than what the loading manuals use and realize I will be somewhat slower. This has been very frustrating. At first I thought it was my chronograph. I recently purchased a Magneto Speed and still the same results. I come to the conclusion it is probably the chamber, throat, or just the barrel in general. At some point I would like to put another barrel on it. [/QUOTE]
