1-10 twist .308

The 10 twist will stabilize heavier bullets but that does not mean lighter bullets will not shoot well. In fact, it doesn't even mean the rifle will not shoot best with a light bullet. It just means you can use bullets of a higher weight (greater length).
 
1:10 is best with heavy bullets.

It will shoot 150s just fine, and match bullets will do better than regular or bulk.

Try some 175's. You might get excellent accuracy and less wind drift, if wind is an issue.
 
My Savage FCP McMillan is a 1 in 10 twist. I haven't shot lighter than 168 gr. in it. But I have shot 168- 210 gr. and it handled them all well. I'm sure you would be fine with most weights available in 30 cal. A friend of mine hunts with 150's in his and it's a 1 in 10 twist and it shoots very well.
 
Lots of F class guys shoot the 185 Berger. Is this strictly hunting or a target rifle? Really need more info as to the use of your rifle.

I shoot 210 Bergers from my 1:10 308win and it really likes them. The muzzle velocity is pretty low but, like diamonds, ballistic coefficient is forever!

This. My Savage 10 and B&T APR both love the move from 168 to 175 to 190. I may go higher but 190 is as good as I can shoot.
 
I found Federal premium trophy bonded tip 180 grain to be the most accurate store bought ammo for my 20" rem700 sps
anything under 180 grain just does NOT group as well...check bergers site for an idea of bullet weight to twist rate comparissons

I use 168gr projectiles reloads in my 20" rem700 sps with very good results. Haven't tried anything else. Will definitely have try some heavier bullets
 
reloading heavier bullets is proving very difficult for me. bullets keep getting stuck in the seating dies...I don't know how they get all that powder in there at the factory. (based on 42gr min load for my powder) I cant even get 35 grains in there without getting stuck! less performance than factory is not what im after

ya bud...i cant even get the minimum amount of recommended powder into the case with barnes 180 grains. i havent tried lighter bullets...assuming theyd be smaller
any help would b appreciated
I ordered VT540 powder and berger 180's yesterday to try different things...
the Barnes that I have are tipped and i've heard recently that some tipped ammo will have seating issues

what do i know...like it says..."newbie"
although i have run at least $1000 worth of every flavor of factory ammo and weight thru my rifle after putting it together, keeping the internal and external conditions fairly consistent to give each brand a fair chance to see what works best. fed 180's won with barnes 178 in second...the rest were a waste of money in my opinion.
Rem700 SPS, Cadex chassis, Steiner M5Xi

I see. Heavier bullets get longer. If your powder wad already at full case, you may have no room. One option is to load longer. Let the bullet be seated further out. This may interfere with magazine OAL, and you need to watch for when a bullet at a certain seating depth starts to engage the lands of the barrel. For example, ejecting an unused round can pull the bullet and spill powder everywhere if the bullet is loaded so long that it jams firmly in the throat.

Most people like +/- .020 from the lands. I'm a zero guy myself right now. (But still learning and tweaking). I'm up to 190s.

You can also consider using lighter bullets until the powder is used up. Or switching powders to something a little hotter. (less powder same pressure)
