For what it's worth, I just did a lot of testing with the 87 V-MAX with Reloder 17 in my 243win this summer and I already had a load with 95CT bullets worked up using H4831sc. Both shoot to 100 yards with bullet holes touching but when I chrono'd these loads, RL17... while it had a slight speed advantage, was nowhere near as consistent. The speeds I wrote down for RL17 in other words were a much greater spread than H4831sc with the 95 combined technology bullets. I haven't tested them both at distance yet, but I'm expecting the 95's (H4831sc) to hold together better. I was also testing Reloder 19 with the 87's, and H4831sc, but RL17 came together the best for me. Haven't done any temp consistency testing yet either. For small varminting work, I'll probably just burn the couple of jars I have now of RL17 with these 87's, but I may revisit the other powders again, or possibly IMR or H43450 also yet before declaring my 87 V-MAX load "Final".
