Thanks for all the input. Update as of yestereday:
The gun clearly likes 155 Scenars over 175 SMK. My 15 year old son shot his best yesterday at a 600 yards F/TR. He said he never had to hold oustide of the 9 ring compared to the 175 SMK's.
He shot a 571-10X off a Harris bipod (I'm getting him a better one) and was high Jr. F/TR and 4th overall in F/TR.
It was a proud Dad moment!
