I have shot sub-MOA groups from my Rem 700 MLS, but it is not a sub-MOA muzzleloader, because it will not produce that level of accuracy day-in and day-out. Sometimes I will shoot groups of 1.0"-2.0", and at times maybe as high as 2.5". That's about as big as the groups will expand, under normal circumstances.

And that is a big issue, as there are a lot of variables associated with muzzleloaders that the average guy doesn't realize. I went to check my sights two years ago and was shooting 5.0"-6.5" groups. I checked the scope mounts, bedding, you name it and could find no culprit. I opened a new box of pellets and fired three shots into 1.3". The box of pellets I was using was from last season, and although closed and stored in a relatively low humidity environment, had degraded to the point that accuracy was non-existant.

Add in factors like perhaps not starting bullets down the muzzle EXACTLY perfect every time, or not cleaning nipples with a nipple pick EVERY time, and it is easy to see how a 2.0" group at 100 yards in a muzzleloader is actually a good thing. Smaller is always better, but not always attainable.
