The difference is the Marlin Micro-grooving in the barrels.
It is inherently more precise. More lands & grooves, with proper bullet selection, means better seal and more precision.
Once the action on a lever-action is Locked...it should have zero movement...the bullet just has to do its job in the barrel....
which means, after the action locks, its all up to the barrel & the shooter.
Micro-groove barrels are why a $125 Marlin 795 can shoot less than dime-sized groups @ 50 yards with proper ammo selection.
Of course, I spent a little time pillar bedding it, doing a DIP trigger job, and put on a target adjustable rear sight from a Marlin 25MN...
So now it makes guys who spent $500+ pimping their 1022 cry when they get beat by a guy with less than $200 in his little ole Marlin.
Of course, getting to know your rifle intimately is as important as the fixins...consistant shooting is truly important.
Annie Oakley used a lever-action Marlin for decades...she practiced until she knew exactly where it would shoot...
and I think we all know how that turned out
If you can hit tossed golf balls 10 of 10, you have a good rifle & a good shooter, takes both to do it
I used to have a Ruger 1022-T...traded it for a 1981 Yamaha XS400 after my 2005 Marlin 60 consistantly beat it.
The 60 got traded in for a 989-M2 after it got toasted consistantly by my 1913 Marlin model 37 Slide-action .22lr.
I still don't know why older guns seem to shoot better than newer ones...but there was definitely something going on
as far as extreme quality in older firearms that the modern ones seem to miss more often than not.
