I have a model 146Ba mossberg and it put 20 shots into .8 inches at 50 yards 2 nights ago. I am at work now so I can't put up a picture of the target, but will tomorrow. Anyhow, My friend that was with me really liked the gun and wants one too. Anyhow, after looking, I noticed that the model 46B's look quite similar and then I saw a model 346B that also looked alike. Anyhow, other than build periods, what differences exist between the 3 different models. (sights? stock size? bolt? wood dimensions? Rifling?) Any help would be appreciated to help our confusion. Mine shoots like a hot laser, and I love it. But if he can choose between 3 genre's of mossbergs it will open up his options to getting one just like mine or similar. What model of the 3 is generally considered the best or most desirable??
