I have a savage 10 .308 with a 1:10 twist. My local shop got stacks of federal gold medal 168 gr and 175 gr sierra matchking ammo in and i went ahead and invested in the 175gr cause i had shot some other 175 s and was already zeroed for them but are the 168's more accurate closer range. I heard 168's are a tighter grouping round unless your shooting past 600-800 yards, then the 175's are better? Whats your guys experience? Whats better for getting tight groups at 100 yards? That being said when the stars align i seem to shoot the 175's well but seem to be tough to get them 1/2in or less.

Their performance is close enough that it depends on your rifle. The 175s are much better past 400 regardless.

They both shoot well for me in my 5r. That being said, my rifle seems to prefer the 168 up close. I don't know if that is specific to my rifle, or is a general consensus, but just my experience.

Depends on the rifle for me. Some of mine do like the 168 better, but the 175 is always close and is always going to be better at distance.

My Savage FCP-K is true .5 MOA with the FGMM 168's and closer to .75 MOA with the 175's at 100yds. That being said after 500 yrds the 175's are the way to go.

like people have said every rifle is different. you can give the same pair of earings to 10 different women and only 6 might like them..
I have always had better luck with the 175's, my rifles have a 1:11.25 twist and a 1:10 twist. my friend has a 1:12 and shoots 168's, but again every rifle is different. if your main goal is to punch holes in paper try them both and see what your rifle likes better. most 1:10 like heavier bullets tho.

Your problems have, with almost complete certainty, nothing to do with the ammo.

Id go with the 175. My savage shoots the 168 gr SMK about a quarter moa better at ranges inside 200 yrds but beyond that the groups open a bit faster than the 175s do. That quarter moa diference means a lot less to me at 100 yards than at 500 and beyond. Also the 168 gr SMK tumbles as it goes transonic, about 800 yrds out of a 20 inch barreled 308, due to the boat tail being unstable (too short supposedly) at said speed where as the 175 gr doesn't suffer from the same affliction. The 175 is a more versatile bullet in my opinion, I could be wrong though.

I only load 175 and 178s in my 20" barrel because it likes them for some reason. It's a stock SPS Tac 20" barrel. 168s and 155s shoot well also, but the 175s are legit .3-.4 MOA every outing. I see no reason to use the lower BC bullets when my rifle likes the heavier pills more. I'd say use the 175s since they will serve you better over the entire effective range of your 308.

On my 12FV, it likes the 168s for .5 MOA at 200 yards with no wind (in a range surrounded by high dirt walls). Haven't shot farther than that.

I do have a box of the 175s (that I bought on accident) but haven't fired them yet. I figured as much they'd be better suited for the long haul, but haven't gone past 200 yet, so figured what's the point.
