rochelle,
Not all excited BUT in hunters safty they do stress that all rifle ammunition is different and each different load is not interchangeable. It is one of the absolutes that, shooters should know.
It makes you seem to be a novice gun owner, nothing wrong with that, everyone has to learn somehow. I don't blame you but whoever you had for an instructor, ok if you never have taken hunters safety then it is your fault! Interchanging ammo that "fits" is a major cause of gun accidents. There is really no excuse for that type of accident.
OK off of my high horse
