MD,
Mine was a small sample of Wby ammo in Wby rifles. 7mm Wby 175 and 139 gr factory loads averaged less than 10 FPS differences from spec. Some .300 Wby factory 180 gr Norma Spitzer (the cheap stuff) actually chrono’d a couple FPS faster. I just bought that for the brass. My previous statement was a bit of a generalization. Happy Trails

PS: I don’t use factory ammo in any of my Wby caliber rifles. Too expensive. I handload TTSX bullets for hunting use with good results.
