NORTHMN, the 92 is a short rifle and the fore end cap may need relieving, also the forend. I really Don't want to start that or shooting with nothing attached to the barrel, etc.
I've only had two leverguns that wouldn't shoot for me, a late eighties Marlin 94cl 25/20 and an Uberti 73 short rifle 45 Colt and they both kept me busy trying for accuracy. Different loads bullets powder configurations et al. Nothing worked. I hope this one is a real and quicker fix.
