What is the optimum twist rate for the .223? I'm looking for a new varmint rig but want to handload some of the heavier bullets too.

Thanks,

Agreed
 
Re: 223 twist rate

1.8 for sure.
You can shhot the longer heavier bullets at longer ranges with no stabilization issues. You might have a problem with the little short 35gr varmint bullets at high velocity, they could spin apart, but I doubt it. And if they did you just slow down a little.
 
Re: 223 twist rate

Even a 1 in 7" twist should work. A 7-twist barrel will usually handle 50-52 gr varmint loads with no problem whatsoever and still give you great stabilization up to 77 gr match bullets or even longer. If you're thinking about the 35-40 gr microdots, that's another story and 7-twist would likely overspin them.
 
Re: 223 twist rate

You'll need at least a straight-8 for the 80's.
A 7-twist might NOT do the 90's.
The 90-grainers suck.
They suck almost as bad as anythig below 52 grains does.
I shoot 80JLK's out of a 7-twist: Stable all year 'round; good to 1200 yards in the summer, depending on altitude.

 
Re: 223 twist rate

1 and 9 twist. If your varmint hunting you'll want to shoot the lighter bullets. It is a good middle of the road twist rate. Depends on how heavy of a match bullet you want to go with. What will you do...more varmint or more long range? Still I own 3 .223's....go with the 1-9.

Graham is right, in a tactical/varmint style rifle, I see no reason to go with anything less than an eight. Varmint hunting usually occupies 50-55 grain bullets, and an 8 with do those fine. But there is nothing wrong with using 60-80 grain bullets either. Go with the 8.

Come to think of it, Graham has probably forgot more than I know.

Re: 223 twist rate

I had a sps tactical 9 twist that would shoot 75 amax's very very well. For some reason I sold. I have since bought 2 more that wouldn't shoot them worth a shit. If you are going to build go at least 8 twist or faster. If you are buying factory go sps tactical and take your chances.
 
Re: 223 twist rate

The only reason to go 1/9 is thats what Remingtons (SPS TAC and 700 Milspec) come with. I have and would go with a milspec (24" stainless barrel) over a SPS Tac with 20" and a flimsey stock
 
Re: 223 twist rate

OK so why are there rifles out there with 1 in 12 rates. What can be expect of them? I'm looking to do some mid range (400-500yd.) shooting. I just read an excellent review on the Howa rifles yet they only have a 1 in 12 twist.

Re: 223 twist rate

The 12-twist is optimized for short range shooting with 55grain factory ammo. They are 100-300 yard rifles. You can stretch them to 400-plus if the wind isn't blowing too bad and your targets are wide.
 
Re: 223 twist rate

How does barrel length affect stabilization? For instance my 16" 1:9 carbine would presumably max out around 62gr (tho some say 68/69 depending). Would a 20" bolt gun for example make a difference in this threshold?
 
Re: 223 twist rate

Does anyone know the point of diminishing returns on the barrel length for the .223? I am talking about for a long-range rig. Is it 20", 22", 24" etc.?

thanks

thanks </div></div>what do you consider "long range" are are you talking long range in general or long range for a .223?
 
Re: 223 twist rate

I guess I'm talking long range in general - which to me would be 500 to 1000 yards.

Where I live and have hunted really long shots aren't normal. I killed a deer at 275 yards once with a .270 and one a touch further with a 7mm/08.

The farthest I have shot a "target" was a water-filled milk jug at 400 yards with a Winchester model 70 in .223. I did hit it!

Re: 223 twist rate

Just had a 27" 1 in 7 twist .223 built this winter, still working on loads and have some that look promising. It is throated for 90 gr. Berger's but shoots 69 smk and 70 gr. Bergers very well, also likes 80 gr. SMK and Hornaday 80 gr.

Have seen a 30" barrel on a .223 but don't feel it would do anything a 26" wouldn't do. For a "handy" varmint rifle that might get carried a 24" would be about the longest I'd want. From what I can tell about your intended use I'd think an 8 twist would do anything you want.
