i've given the 308 lots of thought. i think the numbers, for what that's worth, suggest the 6.8 has 80% of the effectiveness (or something like that) of the 308. not sure what that means or how it's derived. it's certainly a good killer of coyote sized game. but assuming that means killing ability on hogs sized game then i guess i'm losing one fifth of the hogs i shoot. usually the first hog shot goes down so that doesn't matter. once they start running it's usually a crap shoot. if you're sniping one or two from a blind or under a feeder it probably won't matter. for my hunting the 308 is tough to beat.
when i had so many problems with the first 6.8 jamming i thought about going back to the 308 many times. 10 years ago i wouldn't even have considered anything less. even though i'm not toting it over hills or anything, aches and pains make every pound count now. i've never liked the 223 for a dedicated hog gun. you see how many run off all shot up with larger calibers so the 223 just doesn't make sense to me for mass killing - no matter what bullet is coming out of it.
i also noticed the vids coming from 6.8 shooters. the screen looks less disrupted from recoil compared to the 308 and i thought that might translate to faster followup shots. i'm not sure that i notice it under fire though. finally, even though the 308 has been very loyal, it's impossible for a man like me to be faithful to just one gun. i probably should have switched back when the jamming started costing me hogs, but the allure of a new gun was too powerful; kinda like a new girlfriend. sometimes beauty makes you overlook a certain amount of temperament... until you come to your senses.
oh yea... and the high capacity mags!!!!! (that is... when the gun works)
no hogs last night, but....
