Depending on the weight, possibly, but in most cases, accuracy may not be good.
No, but a 38 special will work in a 357
No, there are .357 caliber bullets that are not magnum, but they are in the minority.
If the weapon is chambered in 357 Magnum, you can fire the round in it.
Yes, but please use the correct term- cartridges. Not bullets. A .38 Special is basically a .357 Short, and you can safely shoot .38 Special in a .357 magnum. The opposite is NOT true.
357- as in .357 magnum, is the diameter of the bullets fired in fractions of an inch. It uses a bullet that is 0.357 inches wide.
38 or 357
NO! Grain load to high and shell should be to big to load. Forcing of shell can have deadly results to the shooter. 357 can shoot 38's but not the other way around.
Yes
No. <><><> Above is correct- however, ,38 Special CARTRIDGES can be used in a .357 magnum revolver. The .38 Special is actually not .38 caliber, but .357 caliber. .38 caliber bullets, such as used in the .38 S&W catridge, cannot be used.
The ammunition is called .357 Sig. Most pistols in .357 Sig can shoot the .40 S&W when you drop in a .40 S&W barrel.
The .45 caliber is bigger in diameter. If you mean weight. The .45 caliber is generally heavier. However there are some lightweight .45 caliber bullets that are lighter than .357 caliber bullets. Generally speaking .45 caliber bullets weigh between 180 - 230 grains. While .357 caliber bullets generally weigh between 158 - 180 grains. If you are talking about diameter, the .357 caliber bullets are approximately 0.357 inches in diameter. The .45 caliber is approximately 0.450 inches in diameter. Again, using this measure, the .45 caliber is the larger bullet.
