It's funny that you should post this now. I just talked to a guy at the range this morning shooting a .308. He loves his.
I have a .223 and really like it too. My initial testing sort of showed that it shot about everything well. I'm currently using my short range AR load (varget, 55 Vmax) and it shoots right at .5" at 100 yds. I figure with some testing I could probably improve on it a bit. I've done a couple of long range matches as well, mine will stabilize 77 MK's but not 80's.
I suppose you have to ask yourself why you want the 10 PC. It's more expensive that the savage varmit rifles and the only advantage (IMO) is the 20" barrel. But that's what I wanted so I got it. As far as used, they've only been out on the market for a little over a year (I got mine last April) so they might be tough to find. I can't believe anyone would buy one and not like it.
