Hey Fellas, Brand new to LRH. I am hoping to find some help with load development for the 257 Wby. using the 131 Ace Blackjack bullet. I have 7828ssc and H1000 on hand. I was guessing 64 grains of 7828ssc, but would like some professional help. I am aware that it needs a 1:8 twist, but I'd like to start working on some loads prior. I will be building a 25 WSM in the near future as well. Thank you in advance.
257 Weatherby 131 Ace
