Per krieger:         Available twist rates 1 in 6.5 for 90 gr bullets. 1 in7.7 for 69-80. 1 in 9 for 55-69. And 1 in 13 for 55. (Yep, o.k. no problem with this so far). Available chambers .223 Rem. for 40-69. And 5.56 Match for 70 and up. Huh? Are they trying to tell me something ?  Why not a 1 in 9 in 5.56 for a little faster 55gr?

Yes... 5.56 Match chamber has more leade. Make sense now?

They will do whatever you want, just call them.  They do custom lengths, contours, fluting, you name it.  They have special chambers for single loadcapable 80 grain bullets for long range competition that wont fit in the magwell.  I think a phone call will clear up you r issues though.
