I've noticed the hammer on my 30 year old 50 cal. CVA seems to contact the far side of the #11 caps when I lower the hammer manually, as I do when I'm on stand, to hold the cap on. I've never noticed this before and am wondering if it's possible the hammer beating on the nipple at the range may have rotated the bolster ever so slightly. Seems doubtful as the nipple is undamaged. Any chance I can back the bolster off a hair for better nipple alignment on a gun this old or am I just risking damage to the bolster/blueing? How would you do it? Vice grips with padding?
