I have my dad's early 550. The story...

He sold the GRIT newspapers as a young boy (just post WWII) and garnered a Whizzer motorized bicycle. He told me it would go about 50 mph! Well he ended up crashed under the side of a car. Neither he or the machine were badly damaged. People and machines were much tougher back then.

He lost all interest in the Whizzer and worked a trade with a friend who wanted it. He got a good squirrel dog, the almost new Remington 550, and $7. Sounded like a heck of a good deal for my dad. The dog, $7, and my dad are all gone, but the 550 Remington is still here and one of the guns I learned to shoot with some 52 or so years ago. Don't EVER, EVER, take one fully apart!

They are one of the very few semi-autos that will certainly, and reliably, accurately, shoot .22 Shorts. I used to have this crank device you screwed to the trigger guard like a Gattling gun. I think it was actually called the "ATF Activator"! LOL I could load 22-23 shorts in that gun and zip through them in about 2 seconds! It has been fired thousands and thousands of times and cleaned only with q-tips through the ejection port and surface wiping. They are currently actually selling for $200-$275 on GB right now. One for $125-150 is a cherished deal for sure, $175 is fine if you like it, it's a good gun. Not a lot of monetary profit left in it unless the market goes totally nuts. What does a 10-22 Ruger go for at a discount store?! It's real steel and walnut too, not pot metal or aluminum alloy. The early guns do not have a grooved receiver, later ones do. They also came with a cartridge deflector that mounts to the receiver, but many are missing. No big deal. My gun seems to garner pretty easy 1.5" groups at 50 yds. with most ammo. It's not a target gun but it does exactly what it was designed to do. It's special to me so I'm biased. A part of the family for some 72 years. I personally had a later M552 Speedmaster which replaced the 550. It is not as good a gun, simplified, alloy construction, lighter. But it too has a sentimental connection to me. Gary likes the store brands like J.C. Higgins or Westernfield, all made by the major companies for the outlets. Typically they are High Standard, Stevens, Winchester, or Mossberg made designs.

As to your original question, YES, it will indeed shoot about any RF round you will encounter. CB caps are a manual affair but any Hi-speed round shucks through fine.
