[QUOTE="JakeWes, post: 3107819, member: 127709"] Here is a follow-up with testing WC860 and WC872 in the STW: Custom Remington 700 26" 1-8 twist Arken EPL4 4-16 MOA Fireformed Hornady 375 H&H 1x Winchester Large Rifle primers [ATTACH type="full" width="567px" alt="7mm STW WC872 Load Testing w_ 154gr SP.png"]572541[/ATTACH] [ATTACH type="full" width="567px" alt="7mm STW WC860 Load Testing w_ 154gr SP.png"]572542[/ATTACH] WC860 never showed any pressure, even with a moderately compressed load, but I stopped testing WC872 at 92.0gr because I got a very tiny ejector mark, bolt lift was normal, brass is gtg (also look at the velocity on that sucker!). As we can see, WC872 is significantly faster than WC860, or at least the lots I have, do not take this for gospel. So, moving forward, I will treat WC860 as a slightly slower version of the commercial H50BMG and WC860 as the ancient AA8700. If anything, the WC860 behaved exactly how my Lyman 48th Edition lists AA8700. Happy shooting! [/QUOTE]
