So far, most of my Marlins have been sub-MOA, the lone exception being a 2006 Marlin 60,
which got traded off for a 989-M2, which got them all back into precision again.
The hook with Marlins, is that the 12-lands & grooves are smaller in depth, (Micro-groove)
so one needs to use nice fat bullets to get proper "grab" into those lands & grooves...
if one uses skinny rounds, they end up with less than optimal results...
It truly is a case where being somewhat OCD as far as Micrometer'ing one's ammo
the benefit of which shows rather well on the range
It is quite amazing what one can find out when taking a Micrometer to entire packs of ammo,
how much variation is in certain brands...those 525 packs of Golden Bullets are surely factory seconds...
where in others, precision is valued...and little variation is noted.
