What is the best bullet weight with a 1-10 twist ? I am looking for the best hunting load for my Savage 11 .308.It has a 22" bbl. if that matters.
ETA: For deer sized game up to 300 yards.

Try either the 150 or 180-gr loads.

I'd expect the best accuracy with the 150gr loads.

I'm going for the most accurate load.What about 165?

For deer, either 150's or 165's will serve you well. If you really think you'll be taking longer shots, the 165's would be the way to go IMHO.

For some reason all of my 30-06s and .308s thrive on 165-168 gn bullets. In the '06s I worked from 150 to 200 and they settled on the 165-168 level and the .308s from 150-180 and they did the same thing. If you are handloading follow the usual "10% below max" and you will probably find best accuracy before you reach max. I will trade a tighter group over a few fps anyday. Nothing I point a 30 cal 165 gn bullet at, below 400yds, is likely to get back up over lack of 100 fps.

In almost all of my .308 rifles a I've had the best accuracy with the 168 grain loads. The 175 grain loads aren't too far behind I found most of my guns prefer the 168 grain bullet regardless of the rate of twist.

My Remington 700 seems to really like the 175 grain bullets and it has a 1 in 12 twist! My FN SPR A3G has a 1 in 12 twist and it prefers the 168 grain ammo. My M1A likes the 168 also. The Savage Model 10 has a 1 in 10 twist and still is the most accurate with the 168 grain bullets.

That's my experience anyhow. It's best to try different bullet weights in your gun to see what it likes before settling on a particular load.

I forgot about the 168s.

165, 168, 175, and on not so common occasion the 180's for us... Probably have best accuracy overall with the 168's most often...

Other than the ballistic silvertips (which would be a decent choice), I can't think of any hunting bullets that come in 168 grains. For some reason, 168's tend to be open tip match bullets (which you don't want to use on game). Deer just aren't that hard to drop. I've never had one stop a 150 grain bullet (although they were grand slams... fairly tough bullet construction). I lean towards 165's (and I'm really, REALLY liking Accubonds these days) because they just fly better and buck the wind a little better when you get out past 200 yards.

I'm not sure if you're loading or buying factory, but if you're rolling your own look no farther than Varget powder. Like peas and carrots with the .308.

Hope this helps.

Good info.Keep it comin'.I am running factory ammo for now, but plan to get a press soon to load my own.

That is the best way to get the best load for your rifle - make your own. :cool:

Give the 178 Amax or 175gr Matching and a 1:10 twist for paper. For hunting I'd would run a Speer BTSP 165gr loaded hot (mine are handloaded).

Varget is awesome in 308, but I like RL15 also. RL15 is more sensitive to temperature changes, but its overall a stellar choice for my 168 SMK's.

If I have a complaint with Varget, it's that it isn't the easiest measuring powder ever... kinda big sticks. Doesn't bother me that much, but a lot of guys whine about it. 4320 is a darn good alternative - shorter sticks, but more temp sensitive. Almost identical burn rate.

Also if you're in the 130 grain or less category, you would likely be better served by something that burns a little faster.

I'll also add that the Federal gray/blue-box factory 150 Hi-Shok softpoints shoot sub-MOA in my current .308, and have never been out of the top three factory loads for accuracy in any of the many .308 bolt-guns I've owned over the last few decades (twas a red box waaaaay back in the medium-good-old-days).

Powder sticking? I have never used a powder that sticks in the powder measure. It must be a real problem. :wow:

I have had great luck with 165 grain SP for hunting and 168 gr BTHP for punching paper. Both in my .308 and my 30-06

I take it that your rifles are likely bolt-action?

Not so much sticking as "bridging". The extruded powder is cut fairly long, and it just doesn't flow like a ball powder. A baffle inside a powder measure helps. I use a digital powder dispenser, so it's not an issue for me.


Just pulled this off the web somewhere to illustrate the point:

yes, both are bolt guns. 30/06 is a Savage 110 that is scary accurate for a gun that cost as little as it did. :wow:

The other is a Winchester 70 Heavy barrel .308 that took a little work to make it shoot good.

I do not really know what you are going to be hunting, but you should be able to get accurate loads from 150 - 175gr. You could probably get the 110gr varminter to work. The 1 in 10 twist is to be sure 175 gr will stablize out to 1,000 yards. I do not think the faster twist would harm lighter bullets.

for such a hard-to-find target. The deer should feel special. :cool:
