I would say you did real well. Look the model of Lyman rear sight up. It could be worth more than you gave for the gun. I can not make it out for sure or I would have. That should be a real shooter.

Mine will hit an empty 12ga hull at 75 yds every time, off sand bags.
3 out of five times at 100 yards.
It started a competitive shooting spree in my pre-teens, that ended up in the national championships at camp perry Ohio a few years in a row, in the late 80s.

YES ! THATS EXACTLY WHAT I WAS THINKING OF! Well perhaps a bit smaller.

Lol what can I say I'm not a complete heathen

I catually have a 510 target master I need to get to work on, was left in the woods for a few months and the sock is termite ate and it needs a new barrel as the old one was full of water and rust. Dang thing can still group clover leave at 15yd just no where near where you point the iorn sights

Good job!

I like it!!!

Long barrels and shorts or CBs are about as close to legally silenced without ponying up 200 for an ATF screwing.

We used to shoot those in Jr. NRA. It was a very popular program when I was a kid.

Our old 510 Targetmaster must have been the poor kids version, but was still pretty accurate. On a slow day, no sparrows or starlings.....I could not resist shooting something, so would rest on the side of the barn, and aim at nail heads on a board fence. With a 4X weaver scope, would hit em more often than not. That was at around 40 feet.

When I went to 4H camp, the rifles they used were the same 510. So this 521 must have been the upgrade for the serious shooters? Among other things, much better sights.

BTW, checked and half dozen or more are on GunBroker. Most like yours were $350 and up. Starting bids in the $390 range.

Mjm you where right ! It's a 57rs peep and just looking real quick the cheapest I've seen is $77

Old military training rifle maybe at one time you could buy rifles through the Civilian Marksmanship Program that might be what the T stands for.

Nice find and well done on the trade.

I hunted squirrel with one like it in the seventies, it was a single shot though

You did good and now you can cull a few squirrels for meat in the pot!

Chris

your right Lawdog years ago 4H clubs and some sporting clubs had remington 500 series which came from the CMP and Wolfie i just bought a 580 (replaced the 510 series) for the same money course mine has a Herters scope

Wish I would find one like that

It’s junk, dont waste your money!!

T is for target

they made a TL that was a youth target also

Make sure the throat area of the chamber is cleaned well to remove lead accumulation. I had a really accurate 22 once that lost it's ability to group. I found it was due to a lot of lead building-up in the throat; probably from me firing a lot of shorts and CB caps through it.

With that gun and sight is there not to be a round front peep sight with different centers that go in it.
They are real tack drivers.
