Need data-300wm 180gr SST mag prim H1000 & Acc magpro

Hey guys, I'm new to reloading and don't want to venture off into unknown load data experiments. In 300wm, I have h1000 and accurate magpro with 180gr SST bullets. I have data for this with large rifle primers but not magnum primers and wanted to compare the two down range. When looking up data on hogdgon and accurate website, they have very specific bullet heads listed under 180gr and the charges can vary by as much as 4 grains. Anyone have starting and max load data for these bullets and powders with magnum primers? And I'm assuming most would recommend to trim to 2.60 or 2.61 to allow some jump to the lands....! Like I said, I'm new to reloading so I would appreciate any schooling you have to offer.
