It will be marked on the barrel. You can also call or visit ruger's website.
Depends. If you mean the Ruger Mini-14 or Ranch Rifle, yes, you can. It is chambered for .223 and 5.56x45 ammo. If you read the owner's manual (available on the Ruger website) it will tell you that on page 13. The Target Model is ONLY for .223. Of course, the 6.8mm and the Mini-30 use different ammo entirely.
If that is what is printed on your barrel. Most will fire 5.56 x 45. They are not the same.
The Ruger Mini-14 Ranch Rifle marked as .223 can safely fire the .223 AND the 5.56 NATO military cartridge. The Ruger Mini-14 TARGET model should only fire .223 ammo- no 5.56 mm
I'd stay with standard velocity ammo which it was designed for.
yes. the 5.56 is the 223 caliber ammo.
No. You will have to have a Model 1895
Depends on markings on upper.
no
Yes but I would only shoot those loads with a 55gr.bullet or lighter.I believe the smith and Wesson model 1500 has a twist rate that is not made for the heavier bullets found in todays .223 ammo.
Each weapon will show a preference for a certain lmaker and/or bullet weight. The only way to know is to shoot all the available ones out there.
NO!!!!!!!!!!!!!!!!! DO NOT TRY THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
These were made for Gamble's Stores by Savage, and are caliber .22 LR.
