Cheap bullets and the 257Wby don't mix well. I started mine out on factory 100gr SPs, the cheapest factory ammo available. They worked fine as long as the shots were out at distance, say 250yds and beyond. Killed like lightning. They showed their weakness when a deer stepped out at 40-50yds and the bullet exploded on impact on a broadside shot. I got the deer, but it took a long tracking job and another finishing shot. Extreme velocity is the enemy of cheap bullets, and that's the whole purpose in using the 257Wby. 100gr TTSX and RL22 is the standand load for the 257.
