I haven't cast in several years for a .375 and then it was for a .375 AI. I used a Lyman # 375449 gas check design,which weighs out at about 280 grains using wheel weights.I can't give you the velocities(approx. 1400 fps,easily achievable in an H&H).I was using IMR 4198 with dacron as a filler. Five shot groups ran around 1 1/2 to 1 3/4 inches at 100 yrds.You won't win any benchrest matches with it,but accurate enough for game at reasonable ranges,and just plain fun to plink with! memtb

You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong." -Bob Hagel
