[QUOTE="Rent Outdoor Gear, post: 899998, member: 72470"] Looked up some load data on the Hodgdon website for the STW and noticed that they list their pressures in CUP instead of psi... I assume their CUP listings (around 52000) coincide to loads that are in the 63,000 psi range since the 7mm RUM loads are in the 63 ksi neighborhood and are all listed in psi. Guess their data for the STW is older and they were still testing with a crusher gun?? Would be nice if they would update their data since SAAMI max pressure is now listed in psi for the STW. Makes me want to splurge for a strain gage setup so a guy will really know what his chosen bullet and powder are doing in there... Loaded up about 60 accubond long range pills in 168 and 175 to do a bunch of testing with. Using mostly H1000. Loaded some retumbo also to see how that compares behind the 175s. 18 of them are my best load from my first round of testing. 75 g. H1000 with the 168's and 215 primers. Post results when I get time to send them down range. Planning to employ the OCW method at 300 yards to hopefully find a sweet spot. If I don't find a consistent winner I will be looking to Hart or Rock Creek for a barrel. [/QUOTE]
