MY 257 Weatherby mag rifles like Hammer bullets better than Barnes for accuracy . matter fact my rifle has never shot so well tell i started using 103 gr. Hammer Hunters with Reloader 25 power i have no reason to try anything else speed is 3680 FPS average 3 shot groups at 100 yds. 1/2 - 3/4 groups and so far these Hammer bullets kill well too. these are the rifles of mine i have used 2 - Ruger #1 Brux barrels 10 twist , 1 - Weatherby mark 5 fiber stock Brux barrel 8 twist , 1 - Weatherby mark 5 Accumark 10 twist , 1 pre-64 Winchester 70 lilja barrel 10 twist all custom . these 257 Weatherby mag. rifles all shoot fantastic with these Hammer bullets > accuracy cost money most of the time.
