I'm thinking of having a new barrel put on my model 70. It currently has a 1 in 9" x 26". I'm wanting to shoot some of the heavier bullets so I'm going with a 1 in 8" twist. Should I stay with the 26" length. I don't mind a 26" barrel if its going to give me more velocity. Any brand suggestions?
 
Re: 223 Barrel length

There's not enough powder in that case to make use of a 26" bbl. Or, more accurately, you can't get enough <span style="font-style: italic">slow burning</span> powder in that case to make a .223 play with the big boys.
 
Re: 223 Barrel length

Well... I wouldn't say I'm trying to keep up with the "big boys". I like to shoot and I can load 5.56 cheap. Plus I've got a little competition with a buddy on who can put the most accurate 22 cal combo together to shoot out to about 500 yrds. He's got a 22-250 he's putting together. Yes I know, we could have stepped up the caliber but we are trying to keep it challenging. I already know I can out shoot him with 7.62 LOL.
 
Re: 223 Barrel length

I'd get a 7 or 8 twist barrel ( 7 may give you more options if you decide to try heavier bullets) order a barrel with a 5" cylinder and finish at 26". Half way thru the barrel life you can set the barrel back and recrown and still be at 22" in length.
 
Re: 223 Barrel length

Ive got a sweet shooting mid 90's mod 70 sporter varmint 12 twist 26" I love but 55 gr is as heavy as I can shoot.I would like Ur 9 twist ..want to shoot Fed 69 gr match max. 70gr or up I grab the 243 win. I traded thru 3 or 4 till I got one minty an very sub moa. Wally World ,Fed 200 rd blk white box 50 gr jhps will do .75 Hornady 55 gr TAP will do .5 . CamoCat can vouch he shot it. Long story short if U re barrel I can use a good 9 turn mod 70 barrel.

24.0 with an 80-grainer, or 24.5 RE15. Either should rock in any AR. Watch for pressure: if you blow primers, back off. It can be hard to see pressure signs in a .223 case from an AR until the primers let-go.
 
Re: 223 Barrel length

I agree with Graham, 22 is about as long as you will need. I have two, one Ar with an 8 twist 20 inch barrel, and the other a 700 custom 7.7 twist 20 inch barrel. Both shoot the 75 Amax extremely well,(.2.3 moa on my better days.) 24.5 of RL-15 in the Ar, and 24.0 in the bolt gun.
 
Re: 223 Barrel length

Had a .223 built this winter and went with a 27" 1 in 7 twist Brux barrel. Cleans up about as easy as any barrel I've owned, and that is shooting it suppressed. Can push 90 gr. Bergers @ 2800 and is 1/2 moa rifle with several different bullets.

You have your work cut out trying to keep up with a 22-250. A fast twist 22-250 is the shit for pushing heavy 22 cal bullets. Might look at a 22 PDK, little more powder to play with.
 
Re: 223 Barrel length

Good day,

Free velocity from a longer tube and a milder load is better than short brass life, hot load and short barrel. If you've got access to QuickLoad, find your favorite load and compare at 20, 24, 26 and 28 inches. After 28" it's a case of diminishing returns, but they are still there.

HTH,

Much like the male member, one can have an apendage too long to be satisfying to the other party without painful consequences... but I digress.

Back on topic: Ask the guys experimenting with .338 Norma about the fouling they experienced an inch prior to exit at the muzzle.

Re: 223 Barrel length

Mr. Bronco, you raise a good point. I know that a 22-250 loaded right will out perform a 223 all day. However, and this is a big however..... my buddy will be using a stock savage and factory loaded ammo and will be picking his optic so im not sure about that. Now on his behalf, he can make cans dances out to 440yrds but the fact that he is using basically an out of the box rifle makes me think i have an edge. Plus, my 223 rounds with that long AMAX protruding out the front are quite sexy IMHO...
 
Re: 223 Barrel length

I am running a 24" 1:8 twist no contour heavey bull barrel in .223 (AR PLATFORM)

I have a 5.56x45 NATO spec chamber to allow higher pressures from my reloads and It LOVES 77grain SMK's. I have pushed this rig to 1000 yds with no problems. I wouldn't want anything longer than 24" though.

You might have a chance yet running against a stock 22-250, try to keep the targets past 500 and those high bc bullets will help a lot. Comparing a 80.5 gr. Berger @ 2950 to a 52 gr. match Sierra @ 3800 you really start to shine around 400 yd. By 600 you have half the wind deflection, so pick a breezy day. Good luck!
 
Re: 223 Barrel length

We may be able to push 600 but yeah pm me and ill give you some contact info. He called me today to let me know that he had just put 5 shots in 1 5/16" at 265 yrds. So, I've got my work cut out for me.
