I shoot a left hand savage MKIIGL that has the older style NON accutrigger, this is a great little rifle. it came with a 10 round mag, but i got 5 round mags that fit flush and its a great little target and hunting gun. i have a bushnell 3x9 rimfire scope on it. It groups 1.25 inches at 50 yards with CCI Velicitors. That group is is usually a 3/4 inch group with a flyer. I shoot 5 shot groups.
I just got a marlin 925 basic bolt action that i have my son shoot with iron sights. I'm 48 and my eyes arent the best for iron sights anymore, but in the 50 foot indoor range at my club, i shot half inch groups with velocitors. Someone with younger eyes or a scope would do a lot better.
They are both great rifles that will last the rest of your life if you take care of them. I prefer the Marlin now mainly because i do not like the Accutrigger. I know its very popular, but all it takes is a little twig to get stuck in it and it will keep the rifle from firing.
But both are solid little rifles. The main differeces are the savage is available only with accutrigger, and has left hand options.
the marlin has microgroove rifline which works fine with rimfires, but is only available in right hand.
Both lock up solid, and both have their magazine feed lips right infront of the chamber so feeding is jam free on both.
