I shoot 30 grains under most any cup and core bullet for about 2100 fps and tiny groups in my Dad's old Marlin. I use the 170 Remington or Hornady bullets for paper and the partition for deer. nothing special about the partition, I just lucked into a bunch cheap a while back. I also use the 170 silvertip when I can find them as components, they shoot really well. 30.5 is max in my rifle. I also use 31 grains with 150's in my model 64 for about 2200 fps. Not the fastest, but they are acurate.
