Anyone Lookng for 257 Weatherby Loads?
Got out to the range yesterday. I had good conditions...not to cold and wind was dead calm. I finally sighted in my 375 H&H, which I was itching to shoot for about 6 months now. I also shot my custom 257 Weatherby which always produces fantastic groups. I've attached one 3-shot group from yesterday, which I haven't measured but I suspect is a little over .25". I'm using 70grs. of IMR7828 and Berger 115s. It averages just over 3400 on the chronograph. It's like shooting a lazer beam....very flat.
