Barrel Twist ?

[Bassfish1952]

I've done the 90 eldx and the 90 tgk, in 1:7.5 and they fly great.  More accurate than I am.
A few 6 Arc barrels have come out in 1:8, I've also seen 1:7.7, I think even 1:7...

short answer your 1:7.5 is gtg for sure.

Thanks 
When I saw both the ELDX rounds with a recommended twist it made me wonder.
