To be fair, 1.5 MOA at 50 is still 1.5 MOA at 100.That's my understanding is didn't asked the rep all kinds of questions. She was just reading off the data base.
I had a m77 grouping about a 1.5 at 100 yards and wasn't happy about it and called ruger. The rep said even for that with no optic it should group 1.5 at 50 yards.
I love the older M77's, especially the older untra lights. Great hunting rifle, although I have never tried to get groups of them.
