[QUOTE="shamblin, post: 609713, member: 31477"] My O3 A3 is a custom built target rifle with a heavy varmit barrel chambered in 308 Winchester. It is a 1-12 twist and does not like the 175 SMK. It really likes the Nosler/Winchester 168 BT/BST I get better SD/ED numbers with the Ballistic Silver Tips At 47.6g of CFE 223 and 175 SMK, the average was 2825 fps but shoots one inch groups With the 168 BST and 48.7g of CFE 223 a10 shot string had an average of 2870 fps, ES of 16 and an SD of 7.8 fps and shoots clover leafs under 1/2 inch:) Timgun) [/QUOTE]
