That was the first rifle I ever had. Got one when I was 8. My dad had the stock cut down and I shot thousands and thousands of rounds through it while learning firearms safety all the while. Dad built an indoor shooting range in the basement and I used CB and BB caps down there. It’s an accurate, reliable .22, great find! I gave mine to a friend to get his son started.

I've got two model 512's. Tack drivers

I have been around 3 512s and every one was a real shooter.

Wolfdog, good catch. Those are great rifles. I myself just snagged a Winchester 69A Target. Those old 22's really do shoot well. I will caution you though on the CCI Quiet with the segmented bullet. I have had a couple instances of the slug not clearing the 24 inch barrel of my Remington 121 Fieldmaster. They made it to within an inch or two of the muzzle and had to be pushed out with a cleaning rod. I have also had several that didn't penetrate or expand. Won't use them myself.

So the 521 has a different stock and sights, but apart from that, is it the same barrel and action that was used on the 510 series?

And as for the concept.......a bolt action repeating rifle that will take shorts, longs and long rifle interchangeably......current theory suggests that is not a good idea, yet these rifles have performed well for close to 70 years now. Curious why some modern era maker doesn't take that up and make them like it again. Basically an exact twin to the 512 or Marlin 81, which are tubular feed guns. Seems that greatly simplifies the magazine to handle the different length rounds.

Savage makes some single shot youth guns that are marked for S, L, LR, but not many other's do. And no repeaters.

And with all the emphasis on gun and ammo combinations being made today, I find it almost falling down funny how accurate these old guns were, using the ammo being made in the 50's and 60's. Why reinvent the wheel?

the 44US is similar and took shorts longs long-rifle it has a threaded stud that threads into the bottom of the magazine to allow it to feed shorts , this shortens the mag the stud becomes the back of the magazine

I have the exact same rifle that belonged to my dad.They are absolute tack drivers and that one is in great condition.In my late teens i used it in competition and got my Distinguished Expert ,NRA ranking with it.That sight is way better than any more recent ones and is all steel.The Lyman sight is the first thing I noticed.It is easily worth $100.You made a great buy.It may be hard to scope as the bolt handle wasn't designed for clearance.Magazines should still be available.I even have a couple 10 rounders and all,still function perfectly.Nice find.

You can’t go wrong with these old Remington 22’s. They are super accurate. They had three versions of these that I know of. Single shot, bolt action, and automatic. Be on look out for the rest to complete your collection.

Every time I see this I smile. You made a great deal.

So got out on the porch today and Im so happy I bought this little fella! It's rediclous how much fun this gun is lol.



Top targets are all five rounds at 12yd and the two bottom targets are ten rounds at 30 honestly it's rediclous how much fun this is with some bulk ammo

I am glad you are enjoying it. I wouldn't mind having one myself.
