1in7 twist 223 what grain bullet..

[Donny Fenn1]

what bullet weight(s) are best suited for 1 in 7 inch twist?

 

[canucklehead]

Heavier the better. 62 grn minimum I would say....55grn might not work as well as it would in a 1/9 or 1/12... but then again, I've only owned 1/9 and 1/12!

Again, depends what you wanna do with it!

1-7" twist should work very well with those looonnngg 70-80 grain slugs. Regards, Eagleye.

55 and up. I have 2 1:7 colt 20" AR barrels that even shoot 45 fine (I've only shot the 45 out to 100m, so unknown after that....).

 

[smak_daddy]

get 77 gr sierra match kings if ya can.

1 in 7 could probably even handle the specialty 100gr .224's

 

[t-star]

yea, but they probably won't sit in the mag- single loads only

I had a 1:7 .222 and found that it would shoot all bullet weights from 50 -70 grs very well. The only difficulty I discovered was that some of the 50 gr. light jacketed varmint bullets - such as Sierra Blitz or Hornady SX - would come apart in flight.
