If only using 55's, myself I'd go with 1 in 12.
55 to 68 grain go 1x9" Danny |

1/7 takes any weight bullet.I have both 1/9 and 1/7 and I use primarily 55 grain but do keep 77 and 80 grain around for matches.1/9 should work with bullets up to 69 grain.

No, I have'nt read the ammo oracle yet> I'm going there now thanks.
I am assuming from what I have seen so far around here, that with the 55 gr 5.56 XM 193 I shouldn't see any difference in accuracty between the 1/7 & 1/9. Right? Now, all that is left is to decide on a 16" or 20" HBAR. Advice...opionions...??? |

W/ 55gr ammo, both 1:7 or 1:9 will be able to stablize it pretty well. You shouldn't see much difference.

Longer barrel will give greater muzzle velocity:
- about 25 more yards of fragmentation range with M193 (see Frag charts pinned post in Ammo area) if used in SD or SHTF - less bullet drop and wind drift at longer ranges so likely more accurate if any sort of shooting at 250yds+ is expected. At short range (up to 100 yds), probably no practical difference btw 16 and 20. And certainly the 16 will be lighter to carry and less nose-heavy than the 20. |
