"Accurate" depends on who gets to pick the yardstick. Maybe depends on whether they're buying or selling. I think I've only owned 2 Marlin 1894s. One was a SBL .357. It was accurate but it wouldn't allow more than 1 cartridge in the magazine at a time, they'd hang up on the rim. At that time I didn't have enough guns to have one not working while I waited for repairs so I took it back to the store and they did something or other with it. The other was a cowboy .32 mag. That was a brick but it was near MOA accurate. I didn't enjoy packing it very far but there have been times I wish I'd kept it. Wait, there was another, a plain blued C model .357. I think I just got bored with it, I don't recall it having any problems. Or maybe I started drooling over a Ruger 77/357 and needed to fund that. If so, it's gone down the road, too.
