No. A .357 Magnum revolver (not an automatic, lever action, or anything else with a headspaced chamber) can fire .38 S&W Special ammo, but not .38 Long Colt.
I'd stay with standard velocity ammo which it was designed for.
Your marlin model 925R rifle accepts .22 long rifle ammo.It will handle any standard 22 long rifle ammo made.
In most cases yes it will shoot in your revolver,this cartridge has been around a long time and is loaded mild due to the age of the firearms out there.
The first 45 long colt lever rifle was made in 1985.
Most .22 BOLT action, pump and LEVER action rifles that are fed from a tube magazine will handle shorts, longs, and long rifles. Remington produced several auto loaders that wil handle mixed ammo- the Remington 550 may be the best known.
NO NO NO! Only shoot what the rifle is chambered for and so marked.
