the 308win case regardless of bullet weight is the MOST efficient cartridge there is and i'm not a 308win fan regardless of me having 8 or so i own. just a great all-around cartridge! when i was younger (about 12 to 15 yo) the 308win kinda was scarry to me being a 30cal. the strange thing is i had already been shooting a 264wm since 11yo. sure, the 28cals have a better bc than the 30's do, but the 308win will never die just like 45acp will. i'm not stating a 1911, just 45acp! my 1st firearm in 45acp was a 1911 and it seemed to be terrible until i bought a g21..............that changed my view on that cartridge on how good it is. only bought the g21 cause the ffl owner made me a good deal since he knew i bought a g17. you might not be a glock fan (i'm not necessarily a fan, but do own a few), but that gen4 is very accurate even with wwb 230fmj's. 9's are boring regardless of newer firearms as i have no reason to buy another 9.
