I have known lots of lever guns, almost exclusively Marlins, capable of MOA or very close. Not target rifles by any stretch, but IMO the accuracy isn't the weak link in these rifles. Usually it's the round they are chambered for......
That said, I don't disagree with your point on the Leverrevolution and I do love the .30 WCF, 45/70, et al. I just think the whole 'levers are so inaccurate thing' gets blown out of proportion.............
