Got a 257 Bee coming today, love new rifles, never shot this caliber but have been reviewing a ton of loading data and the high velocities of this caliber. Most streamlined bullet appears to be the Berger 115 but I noticed a lot of gents have elected to drive the 100 grain Barnes TTSX to 3600 fps. Other bullets I have are the 110 grain Accubond and 110 grain Hornady Innerbond, real question, mono bullet at high speeds or lower speeds with cup and core? Any failures of the TTSX to penetrate and mushroom? Mostly big whitetails up in Alberta but could be the occasional elk or bear. Best direction to start loading in?
