[QUOTE="Plinker147, post: 1180870, member: 88320"] I think the Sendero (#6ish depending on barrel maker) Contour is about when you start seeing better accuracy in larger calibers say bigger than .264. Smaller the caliber the more meat on the barrel even in lighter contours so it doesn't seem to be the same. I have sporter #3 type contour in 25-06 and it shoots the same for 5 shot groups. I have lighter barrel on a 8mm Mag and it starts to spread after the 2nd shot. If your shooting 20 rounds in a row like F class then you will notice a difference between #6 and full heavy barrels. But for hunting I like the #5-6 contours seems to be a happy medium from accuracy and carry weight [/QUOTE]
