1 in 10 will work just fine for you. Hornady now offers some good stuff in the 208 range and the berger 190's are pretty nice. You'll find a 26" prefit pretty easy but you might have to put in an order if you want a different length. Have you considered at muzzle brake yet? If looking for a brake and barrel give Devin at Sinarms a shout. You should get pretty decent turn around time with him and get can do the brake for you while he is at it.
