Xlpushy, are you sure that you loaded or have loaded 7 mm rem mag with H110 or H380, these powders seem awful fast for that magnum cartridge. Imr 4350 is probably the fastest that I use with 150 grain bullets, but I use IMR 4831 with 140 grain Accubonds to very nice results. I tried the H4831sc with 150 grain Swift Sirrocco II's and the minimum powder charge gave me "hard bolt lift" so I abandoned it after three shots.
Thanks for coming!
