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.
No. Never attempt to fire ammo in a weapon not designed for it. Dangerous.
The gun is likely a Harrington & Richardson (H&R) model 925. The caliber is .38 Smith and Wesson (S&W) special, not to be confused with .38 special (SPL). You must shoot the .38 S&W ammo, not .38 spl.
