My 32 Rem , rimless sister , likes a case full of IMR 4350 with a plain base Lee 323-175 2R in this case the 323 sizer is right on at 323 and a perfect FIT in the 316x321 Rem 14 . I use a modified Darrs , grease em' up push em' through load em' . The slow powder comes in around 2150 fps just over 30kpsi , that's about where IMR 4350 cleans up .
