Even when the company's were seperate, the loads were'nt that much different. Now that their combined, probably like 296/H110. I wouldn't bet against it! I'll do just like I've done for 35 years. Start at the bottom of the load, and work my way up. And that even means just using the same powder, just changing lot numbers. Back when I was shooting silhouette quite heavy, A different lot of IMR 4895 gave me the same results in my 7br with a grain less powder. (kinda nice, as that gave a bunch more loads out of an 8#keg) gypsyman
