I have a bit of advice for the OP....patience is a virtue, and arguing incessently with those obviously more knowledgeable than you is never a pretty picture. I can understand a thirst for knowledge, but do we really need 4 or 5 threads.....created within hours...comparing this cartridge to that cartridge? To make a long story short, theres a variety of calibers out there so people can buy EXACTLY what they want. Yopu might want a 300 Win Mag....I might want a .308....NEITHER one is BETTER than the other, it just depends on what you want it for, the ranges you shoot at, etc. Asking for comparisons will get you a lot of opinions, but NO ONE can definitvely say that caliber x is better than caliber y without knowing what type of gun, what kind of hunting/shooting you do most often, etc. Different cartridges fill differnt niches. If I hunt deer somewhere where my longest shot is no further than 150 yards, I don't NEED a magnum 30 cal to kill my deer....even the lowly 30-30 is more than adaquet at those ranges, and is effective without the added recoil, muzzle blast, or COST of killing that same deer equally dead with the newest wondermag out there. Yeah, the 300 winnie may have imporessive ballistics, but high performance...when its not needed....is money wasted. If you never plan on drving faster than the speed limit, a Ford Focus makes more sense than a Dodge Viper.....right? Getting angry or arguing the responses to your threads doesn't 't help battle the perception people are getting of you. While it never hurts to ask an honest question, posting questions as a pretext to an argument you seemingly want to have is in poor taste, IMO. If you don't want to be labeled as a troll by the membership at large, maybe you could/should rethink your attitude and how its being precived by others.
I'm not trying to ruin your fun here...quite the contrary actually. If you want to be respected, take a more respectful tone with your posts, and maybe hang back a bit and see how other members conduct themselves in conversation. Using a little discretion in what you say and how its said goes a LONG way towards peoples impressions of you....
and now on to a point of fact:
i think theres a reason the army rejected the 223
Really? They did? Last I checked, the 5.56 is our standard military round....and guess what, the 5.56, for all practical purposes, IS the .223 remington round. AS a military superpower, we are ALWAYS looking for the "next best thing" in a weapons system, but to state the army has rejected this round....when its currently in use in two major conflicts as we speak.....and with m-16/M4's being our standard infantry weapon....is grossly erroneous
