Yes- a very good deer rifle.
Generally speaking, no. You can only fire the caliber for which the gun is chambered. There are some exceptions, but not many.
looking for info on Winchester model 280 in a 22 caliber simi-automatic. when made and value of the gun now. Thanks
the 12 guage is a caliber not a gun
.28 and .280 are the same diameter bullet. I know of no pistols in .280, with the possible exception of some of the single shot pistols that fire rifle cartridges. I know of no cartridge called the .28.
Contact SIG.
Standard Vanguard is about $400. My references do not show they were made in .280 caliber.
a .45 caliber.
What caliber of man are you looking for? What caliber of gun are you looking for?
The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
It is the standard .68 caliber
Caliber has nothing to do with it.
smaller the number, the smaller the caliber.
