I recently acquired a new Magnum Research BFR. I have only had a chance to fire a few cylinders of ammo and, so far, it appears to be a revolver I am going to like. The question I have is this, in handling it this morning I discovered that I can cock the hammer before the cylinder is locked if I cock it slowly and "gently." As long as the hammer is pulled back with a more usual motion it rotates the respective chamber fully into line with the bore. Pulling the hammer back completely to the point where it comes to a stop also brings the cylinder to complete rotation and lockup. The problem is one which is very unlikely to cause a problem in actual use as far as I can tell. Still, I am a bit concerned about what might happen if the gun was discharged when the cylinder is not locked. I think the alignment may be off by as much as 0.040" or so.
As a sidenote, I did refer to one of my Ruger single actions which is about a dozen years old to see if the less expensive gun showed any similar issues. That one, a six-shooter, could not be made to do it under any circumstances and it has been hammered by thousands of rounds of both heavy and standard loads. I can't imagine that the newer BFR will improve over time. Thoughts?
