Yes, a .38spec +P will give you light .357mag velocity.
No, the only .357 auto is a Sig. Different shaped chamber.
NO,NO,NO,NO,NO.........you CANNOT shoot the 357 cartridge in a 38 special, but you can shoot a 38 special cartridge in a 357 pistol.................the 38 cal. cylinder was not made to house the 357 cartridge or take the pressure.............
a 357 cal. revolver cartridge WILL fit a colt 357 python. Also, a 38 special will fit a 357 cal. python. The 357 sig cartridge will NOT fit a 357 colt python................ The 357 sig cartridge ONLY fits the sig model pistol For clarity.....the sig 357 is a pistol. But, the 357 python is a revolver................
There are a dozen different cartridges with 38 in their name, and SOME are compatible with the .357 Magnum. A .357 will fire .38 Special, .38 Short Colt, .38 Long Colt- but NOT .38 S&W.
.17....22 Cal....32 Cal....38 Cal....9mm....40 s&w....357 m......44 special....44magnum...45 Cal....454 Cal.....500 magnum......50cal
No, there are .357 caliber bullets that are not magnum, but they are in the minority.
No
.38 Special cartridges may be safety fired in a .357 Magnum firearm. The .38 Special is actually not .38 caliber, but is .357 caliber. After shooting them, it is a good idea to scrub the chamber well, as the shorter .38 Special may build up a ring of fouling that will make chambering .357 cartridges difficult (until it is cleaned). .38 Special is basically a .357 Short. This does NOT apply to other .38 ammo, such as .38 Super, .38 S&W, etc.
357
the 40 cal is a little bigger then the 357
The .357 has a longer case and a heavier bullet; it is identical to a .38 in diameter but far more powerful. This is why a .38 will fire in a .357 but not the other way around.
