    Im wondering if 1-10 would be best twist rate for a .22-250, I want to shoot 55-60 grs only.

    That's what I have & it shoots lights out with 55 gr.Won't do well with anything over 60 grs or at least mine won't.

    G -

    Howdy !

    IMHO......
    With enough vel, 1-12 oughta be good for up to 65gr.
    Keep the custom 60s under .75" long, and 1-12 should be fine.

    Looked at the Berger site, now Im confused, my google search is giving me all sorts of results, some say 1-10 some say 1-12 others 1-14. Anyone else able to confirm that 1-10 is what I need for 50-60 grain bullets.

    Most factory rifle have 14" twist and are designed to shoot the 50 to 55 grain bullet weights.

    My Remington 700 has a 14" twist and shoots 50 and 55 grain bullet in 1/2 moa range.

    If varminting is your goal, I'd opt for the 14" twist and use 55 grain bullets which should yield excellent accuracy at the higher end velocity range of this cartridge.

    With the faster twist of 10", you may have to use a lower charge weight thus lower velocity to obtain acceptable accuracy.

    My 14 twist 22-250 would shoot 55 grain bullets into decent factory rifle sized groups, but would not shoot 60 grain Nosler Partition bullets at all. Groups would double or triple in size. The 12 twist is probably optimum for 60 grain bullets, so your 10 twist would handle even longer/heavier bullets, but as K22 points out, you may have to give up some velocity or accuracy.

    I have a 22-250 in a 14 twist that shoots the 55's well, but if was going to get
    a new one, to shoot heavier, I'd get the 1 in 9 twist thats popular & would handle 55 - 75gr. ;)

    Gamma, one reson for the various answers you are getting is that weight is not the problem as much as bullet length, base to point.

    the longer the bullet (higher bc) the higher twist it takes for the weight.

    the factory 700 has 14 twist and is fine with most bullets b ut becomes questionable with the balistic tips as they are longer,

    i have a hart 13x twist and it is a .100-.200 shooter with the sierra 55 Blitzkings, a long bullet.

    what you need to do is consider the lengthof the bulletyou want to shoot and then sellect a twist, However your choice of 10x should cover the wide range up to the mid 60's weight while being overkill for the 55 blitzking and simular length bullets.
