You will have to shoot both to find out.
yes
38 Special. Stay away from +P
NO
Yes. Accuracy may be better in an IC choked barrel, but they are safe to shoot.
You can, but, you should not. The frame is not rated for +P
38 Special; yes.
if think when you put a 357 cartridge in your model 637 the tip of the 357 'might' stick out the end of the cylinder. that tells you NOT to shoot 357 cartridges in a 38 special..........
it does shoot the 38 spl cartridge.............
Thye smith&wesson model 28-2 was chambered for the .357 magnum cartridge.I would say Start with the one round that you and the gun shoot best.Then you can experiment on different weight bullet loads.You may also shoot standard .38 special loads in your model 28.
Not desgined to shoot the 22 WMR
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.
You can shoot them in a .357 Magnum revolver, but that's about it.
