I am thinking hard about ordering the 6x6.8 but i see they have 2 twist rates.
which rate is the most accurate? looking to shoot 75-87gn bullets. so i would assume the 1x9 would be the appropriate one.?
also are the longer barrels worth it for more speed? or is a 16-18" good?
most my ar's are 22-24" i like to get all i can out of a round with accuracy and speed with accuracy being #1

My 22 inch barrel gives me 3550 with a 58gr Vmax. It will push a 75 at 3260. A 24 inch barrel will be faster by at least 50 fps. That being said I prefer the 22 as the best over all length. The 16 inch upper I just built is uncomfortable to shoot because it is so LOAD. Speeds out of the 16 are comparable to a 20 inch barrel chambered in 6X45. |

The 1:10 will shoot everything up to 95 without a problem. It actually might be faster for the light bullets as there is less resistance going down the bore with the slower twist. Barrel lengths won't change. I have them in 18, 20 and 24 in the 6X68. I tend to always go at least a twist faster than I need as bigger bullets seem to always appear just as you bought the optimal for what you have. Just like a 1:9 223 the 1:8 is needed to do the big boys and then they got bigger and a 1:7 was needed. Remember I to ONE twist not TWO as if you jump too far the little guys just don't seem to be willing to do bug holes like they do at a slower rotational rate.

How would a 1x9 do with say 105's?
