The 10/22 magazine hold 10 rounds and is flush with the stock.
It's a personal thing I guess but I absolutely hate those Ruger round mags. That's one of the biggest reasons I prefer a Marlin 60. But the Savage is a bolt action with a box mag that will hang down if you use the 10 round mags. The 5 round mags don't hang down as you said. I guess that could be a deal breaker for some but the rifles are just so different I can think of 100 different reasons for preferring one over the other. It boils down to whether you want a bolt action that's really accurate or a semi-auto that's pretty accurate IMO. But the OP said he has a $300 limit so that leaves out any major upgrades to the Ruger. So IMO the Marlin 60 would be a better choice if he wants to go with a semi-auto. Of course he might change his mind down the road. That's why the real answer is (always) get both or all three or 10 or 12. I have so many rimfires it's ridiculous. I like them all for one reason or another. That first rifle should be free anyway. You know how they give heroin out to kids for free until they get hooked. They're gonna hook you anyway. It only seems fair that the first few rifles should be free.
BTW I think the 60 is allowed in Californistan. I saw some guy go through the process of checking them out for CA just recently. It was something about the mag not being removable or something. But don't take my word for it. I'm no lawyer and I've never been to Californistan.
