Thanks for the input;however, speaking for myself the terms firearm, rifle, pistol and gun are all basically the moral/cultural/legal equivalent of weapon and I never felt a need to be bashful about it. If it is not illegal, so be it. I do have a problem with the illegal use of anything described by all of the aforementioned terms.
To quote Ted Nugent, if guns cause violence, mine are all defective. Since the original question involves a decision of pellet gun or .22 smallbore for shooting steel ( it's legal ) and proper selection, I can't see reason for offense by anyone other than PETA or the anti gun wing, neither of which I worry about. The same would apply to a .308 for silhouette shooting (gonna stick with that term also).
To make another point, we're not talking about prostitution, theft, lying under oath while holding the oval office... This is in reference to reduced scale silhouettes with reduced scale instruments (sounds a bit silly). An additional point, good thing we have the term silhouette to keep PETA at bay. We really wouldn't want to use terms like ram, pig, turkey or chicken.
