good info,
so would you say the more revolutions a bullet makes the less distance it may travel due to friction? (I am in a physics class this term) which it sounds like you are explaining Saxon. At the end of the day which is a better twist for a common AR a 1/6 or 1/9? 1/9 is more common right?
OK saxon has taken care of the smart stuff. All I can add is both of my ARs have a 1-8 twist and I have shot every grain I could find through them with no negligible difference in accuracy. (55grain thru 78 grain)
So I would say go with the "in between" twist at 1 in 8
lol yes but i grew up and went back to a real mans man of a cartrige back to 30-06 and 7.62X54 and 7.62X39 lol
1/6.....1/7...1/9....1/12...etc...the number of revolutions the bullet makes in an inch. The faster the twist rate the faster it will stabilize.
Which is better and why depends on the caliber/barrel length/bullet weight etc
1/7 is good for 62grain and up
1/9 is a very typical twist and will turn a 55 grain bullet well
1/12 is slower and will turn lighter grain bullets
If what you are getting at is buying a ar in another caliber other than 5.56 I doubt your gonna find a big selection on twist rates. My ar in 7.62x39 has a 1 in 12 twist and I think the only other option is maybe a 1 in 10. The 6.5, 6.8, 9mm, ect, ect, wouldn't surprise me if they offered only one option.
