I'm afraid I have to both agree and disagree with the preceding posts regarding grammar and style.
I have no problem, generally, with loose or nonexistent grammar and style when it comes to casual communication between friends. Much of the traffic in forums like this one consists of just such messages.
However, that doesn't mean such things are unimportant. Sometimes, posts containing no punctution, one long run-on sentence, and bad spelling are virtually impossible to understand, let alone answer intelligently. When discussing technical matters such as load data, clear communication is not just a matter of clarity but potentially of damage to firearms and/or shooters. And I get particularly upset when, as is often the case, I see posts pertaining to Second Amendment issues (usually forwarded stuff introduced by, "A buddy sent this to me -- pass it on!") that contain outright plagiarisms and false attributions (such as the supposed "Hitler speech" about gun control that Hitler never uttered, or the wonderful "Why I carry a Gun" essay by "Major L. Caudill, USMC ret.", who did NOT write it and may not even exist), or lousy spelling and grammar. These things can and do sometimes "go viral", becoming widely distributed, and they do nothing but serve up ammo for those of the anti-Second Amendment crowd who are always keeping a sharp lookout for evidence that we are the illiterate, lowlife boobs they wish to portray us as, anyway.
So when I see terms like "clip" or "bullet" or "caliber" being used improperly I try, as tactfully as I can, to correct the writer. I figure that, after all, the person is usually asking to be educated on the subject he is inquiring about, and so I try to do my best to accommodate when I can.
