I have a lot of h870 powder, I have load data from a manual.the print date shows 1996 for 7 stw and others I can be used for especially 257 weatherby. I need help for using this powder for the 7 stw in the 140 grain, and 150 grain ballistic tips and partition. I guess it is because takes too much powder for the bullet weight.just guessing. I wanted to use it and may not have it used up before my eyesight starts getting fuzzy.i hope never on the sight, I appreciate this help very much LRH,buck in n.c.
