I am gearing up for a new varmint rifle for the fall coyote season. I am looking at a couple shilen 6mm barrel blanks for a 6BR or a dasher. Anyway one barrel is a match grade and the other is a select match grade. There is about $60 difference in price. Should i go with the higher grade of barrel or do you think the standard match grade will be ok? Both barrels are stainless 10 twist 6mm blanks. thanks guys, Lee
