Absolutly, The 6mm Remington is a great caliber and is very similar to the .243. You should have no issues taking down any North American White-tail with the 6mm. It is also a low-recoil and accurate claiber.
Impossible to answer. Are you referrring to a 25ACP or 9MM?
It depends on the particular model of the rifle, not the caliber it is in. What model and make is it?
Yes, Remington did produce the 6mm Sportsman 76, which is a variation of the Model 760 pump-action rifle. The 6mm caliber version was introduced in the 1970s, catering to hunters and sport shooters. This model is known for its versatility and was part of Remington's line of firearms designed for various game hunting.
Usually not. A BB is .17 caliber and a 6mm pellet would be .236 caliber. That means that a 6mm BB gun would be imaginary. There are .17 cal. pellet guns and there are .22 cal. pellet guns. You could drop a BB into a .22 cal. pellet gun and it would probably be ejected if it didn't roll out the barrel first. Always read your owner's manual and become familiar with the recommended ammunition and operating instructions.
The .24 is not the caliber all airsoft bb's calibers are 6mm the .24 is the grams which is how much it weighs.
