Love my 527 .223 varmint laminate and my 550 .380 win Kevlar. Looking at the possibility of special ordering a 550 American in 6.5x55SE. Anyone have one? Or a line on where to purchase one without special order? CZ web site doesn't list the twist rate. Is it a 24" barrel in 1/8 twist? Any other first hand user comments appreciated. Alternate might be a Savage Weather Warrior chambered in 260 rem, or 6.5 Creedmoor, or 6.5 284 Norma. Think I'd prefer the 24 in barrel and larger case of the Norma, cost, wt, and other specs being equal. I reload but not yet for any 6.5 cal. Thanks
