270 twist rate
@ 02:16 am (GMT) |
john feyereisnI have a rem 700 in 270w i am considering rebarreling. A 10 twist is pretty standard, i would like to shoot the hogher bc 150 grain bullets, i am leaning toward a 9 twist barrel, i know most or all 270 bullets will shoot ok in a 10 but i am thonking the higher bc 150s certainly would not be hindered with a 9. I really dont think it would hurt much even with the lighter bullets. I coild go with an 8 as well, but an 8 might hurt performance with lighter bullets.What do you think? Does a 9 twist make sense? |

Bryan WebsterRe: 270 twist rateGo to Berger Bullets web site and use their twist calculator for your bullet and speed. You will have to enter everything manually as I do not think the .270 cal is in their bullet list. To me it looks like the long heavy 150 grainers or better would do well with the 1:9 twist, but I would wait for Nathan's advice on that. |

Nathan FosterRe: 270 twist rateHi John, it would work fine. Of the heavy pills, just be a bit careful as some sleek designs are not all they are cracked up to be at present. If you really want heavy pills, go with the .280 / 9 twist to widen your options. |

Thank you guys for the comments I have never owned one, but on paper i really like tge 280 rem, however i own a couple 270s and a 7 rem mag. I inderstand the appeal of the 280, but i would rather not fuss with brass and dies for another caliber. |

john feyereisnRe: 270 twist rateAfter shopping around a bit, it seems my choices for a 9 twist 270 barrel are a xcaliber, or for another $100 or so i can get a Kreiger. I have heard good things about the xcaliber barrels and they should be an upgrade from a factory rem barrel. A kreiger from what i can see seems to be a top of the line barrel with many on competition rifles of all sorts.On one hand I could justify the extra cost, if you spread it out over the life of the barrel an extra $100 for a top of the line blank doesnt seem to bad. On the other hand I question wether I, an average hunter witha sporter barrel rifle would see any difference in a slightly lower cost blank. Simple luck of the draw could come into play as well. Any thoughts on the make of the barrel? |

Bryan WebsterRe: 270 twist rateNot many make the .270 barrel in a 1:9 twist. I know Kreiger does however.you are best to phone the barrel makers and ask before committing. |

john feyereisnRe: 270 twist rateI found the thread about the cow elk taken with the 6.8 and the prototype copper bullet. That was interesting, a winchester xp3 bullet that has a front half of solidcopper and a terrible experience with it is the reasoni am here on this site becoming a bullet nerd. I will poke around over there some more and see what i see |

Mike DavisRe: 270 twist rateyip thats the one...slimjim has done a heck of alot of projectile testing...he puts a jug of water infron t of his bullet trap box...not as good as Nathans goats but they few and far between in the states....just about every .277 cal projectile has been given a work out,I will go and see if I can bump some of his other test threads for you. |
