I seem to be having trouble finding info on a 180 btsp (speer) in a 300 win mag using h1000 or h4831. Still relatively new to this, but I don't think I can accurately use data for similar bullets with those powders right? I haven't loaded any 180s yet, just 165, but want to go bigger. I did see that the h1000 often causes a compressed load, which noticed even on the 165 grain due to seating depth for that particular rifle.
Also, looking for 165 btsp data for a .308 win using h4895 and varget. Any advice is appreciated.
