Gun Question
 

Will dry fireing a center fire rifle hurt it.

RE: Gun Question
 

No. Unless the gun has some inherent problem or weakness, it should cause no problem. I wouldn't advise anyone to do it repeatedly , like say, hundreds of times per year, but even that is not supposed to be a problem on a gun in good condition. many shooters practice getting a feel for thier triggers through dry firing. If you're worried get some snap caps.
Rimfires rifles are another story altogether, as are all pistols.

Ask a competitor how often they practice by dry firing. You'll be surprised at the hours they put into it.

Worth hearing what others have to say.
I always use my home made snap caps. Pop the primer out of the spent case and install a eraser from a maniacal pencil you can buy at office supply stores.

:D Al

If there's any centerfire rifle you shouldn't dry fire, I'm not aware of it, and I'm sort of familiar with just about every platform out there!

Why take a chance? Snap caps are cheap insurance nothing bad will happen and I leave them right in each firearm in the safe.
