10BA .308 Steath bullet weights

**tenth_gen** · 04-24-2020, 09:33 PM

I recently bought a new model 10BA Stealth chambered in .308 Win. Based on your experience with model 10's with a 20", 1/10 twist heavy barrel what grain bullets tend to work the best with my rifle. There's quite a wide range of weights available and it would be nice to narrow it down.

I realize that each rifle has harmonics that are unique to that particular rifle but I was just wondering what a good starting point would be.

Thanks

175-178 are what my .308 1/10s like. I've bought a couple boxes of atips that have not worked up yet but I'm reading people are getting impressive results so I'm excited to see what a 250gr does

It really depends on how much you want to spend and what your accuracy needs are.

For economy I like the Hornady 168 g AMax bullets. They seem to shoot just as well as the Match Kings and are a lot less expensive.

I started out with 175gn Hornady's and Sierra's. Then went to 155 SMK's. Then to the AMax. If I wanted to spend more I'd try the 155 Scenar's.

But, these days I shoot cast bullets. More fun to play with :)

I have found the same as Ted. The 175 Matchkings are an economical accurate bullet that is easy to find a node for with many powders. Depending on distances any thing from 150/155's to 190s + will stabilize.

The 175class is the sweet spot for most shooting though. Go lighter if you are recoil sensitive to the 175's

Thanks for the replies. I live in Vancouver, BC and I just did a quick check and I can get Federal Sierra 168gn, 175gn and Hornady match locally and online. Not cheap at $1.80 a shot but I knew this wasn't going to be like 22LR LoL.

Thanks again

I've had best results with 175 smk and burgers, the eld 178 is a good opinion, i was getting slightly less tight groups with them but that could have been me. If you looking for ultimate in accuracy go with berger pills. 168s seemed to scatter a bit, strange thing is I had some mil surplus 147gr and they were very accurate, as almost as accurate has the hand loads i worked up with smk and berger

$ 1.80 per shot, tell us that these are factory loaded rounds ??
As other have asked, At What distance are you shooting at, and what accuracy are you trying to achieve ?

What load did you use on 165-168.. mine doesn't seem to like those. I get at best 1-2 moa, but 175 smk and bergers I get 1/8moa almost same hole.. i guess to be fair though I have not tried 168 since I rebarreled with a shilen on one and criterion on another

So far with 175s in the shilen and criterions, its been harder to find a load they don't like then finding one they do lol

I have two Savage Model 10 .308s, both with 24-inch barrels.

Both shoot accurately, with a variety of weights, but when you measure lots of groups, I discovered what I didn't expect.
One shoots 150 to 168s better than 175s and heavier and the other shoots 175s to 200s better than the lighter 150s through 168s.
Both shoot 168s about the same.
Both with Federal GMM SMKS and with hand loads using Sierra SMKs with different powders.
The rifles show a preference for weights and the weights are different.

I have three Savage 6.5mm Creedmoor rifles. Two shoot 142 to 147 grain bullets the best and the third shoots 130 and 140 grain bullets slightly better.

It depends on the barrel in an individual rifle, IMO.

Better try different weights to be sure.

I know the steel type is a big factor as 416R has a whip frequency thats different from say 4150 but each alloy givin that it is compared to the same alloy resonates at the same frequency. Are both barrels you are talking about the same steel?
