    Can anyone help me out here.? I was thinking of picking up a new Savage 12 fv in .223 with a 26 inch 1/9 twist barrel. What's the heaviest bullets 1/9 will shoot...? I like the 77gr SMK...

    Thanks in advance.

    My 9 twist .223 shoots 75 AMAX very accurately and consistently. The 77 SMK is shorter than the AMAX, so it should work, too.

    Itll shoot 90’s if you rethroat it. The way they come theyre suitable for 52gr seated at ar mag length. I have a 223rem throating reamer just for this purpose

    Right on the packaging Sierra notes 7" & 8" Twist barrels only. That is not to say accuracy will suffer greatly, merely that Sierra suggest a faster twist than 1:9 for that bullet. For the 69 grain HPBT Match they suggest 1:7 to 1:10 twist rates. My best advice would be to try them. Right now Cabela's is having a good sale on the Savage® Arms 12 FV Bolt-Action Varmint Rifles.
    Regular Price: $419.99
    Sale Price: $369.99

    Then a $100 rebate offer in the form of a pre paid VISA gets it down to $269 and use the pre paid VISA towards a stock. :)

    Did you consider 1 in 8?

    I bought a 12 FV .223 last year. Out of the box it shot really good with Sierra 69 TMK and Berger 70 VLD. I had it punched out to 22-243ai and It shoots 75 Amax really well now. I never tried the Amax before it was re-chambered.

    Ya that one on sale at Cabela's $269 is the one I was thinking of buying , I think it not going to happen now.... I just can't justify another rifle or pistol right now... But darn that's hard to pass up...

    I have a Dakota 223 with factory Douglas 1-10 twist. I won a 600 yard match on the 300 yard target at 600 yards. I was shooting 80 grain Sierra. Our elevation is 5300 ft. Thin air helps. Score was 100 8X that tied range record. You never know till you try! Tom

    If your range is located on Pikes Peak (14,115 ft) you can shoot just about anything you can stuff into the case and still fit the chamber. Otherwise, the Berger Twist Rate Calculator http://www.bergerbullets.com/twist-rate-calculator/
    can help give you some idea of the probabilities before you invest in a big box of bullets that you may only end up selling.

    It's the length of the bullet more than the weight that determines stability for a given twist at a given air density. Your 9 twist 12FV should shoot the 69 gr TMK at 750 yds very well. The 53 grain V-Max will shoot impressively all the way to 500 yds. The actual twist rate of your barrel, the altitude and temperature of the range, bore smoothness, neck run out, all combine to help or hinder your efforts.

    The Hornady 75 gr BTHP shot splendidly out of the 1/9 I had a few years back.

    The 73 grain Berger does real well in a 9 "

    I have shot 80 Nosler CC's and 80 Berger VLD's. Both worked well.

    Lower velocity out of a shorter barrel and twist tolerance.
