[QUOTE="Mikecr, post: 551993, member: 1521"] Your X-Bolt is a hunting gun & built to function in that regard. A comfortable, well balanced, light weight carry rifle, -rather than a long range precision gun(just the opposite). If you were to build an actual long range gun, you would be advised against going with excessively short barrels(which 23" is for capacity & LR bullet use). It's not that you couldn't get 'good enough' velocity, but that your muzzle pressures are too extreme for clean release of higher BC bullets. This hurts accuracy. Just consider that fireball at the end of your barrel on firing, and how that pushes on boat tails. Any slightest imperfection in the crown has greatly amplified affects with this. Then there is higher ES, because you haven't enough barrel to burn up that amount of powder consistently. My QL is down right now, but I'm sure a WSM's powder is not all burned in 23". Even a 6PPC at 22" requires very high pressure loads to burn up it's teaspoon of N133. With the implication that you should have longer barrels for that cartridge, I think you recieved good advice. I'm glad your gun shoots well up close, but when you go to long range shooting don't be surprised if performance falls off quick. [/QUOTE]
