My deer load for the .35 Whelen is a 225gr. Sierra or Nosler bullet over a moderate charge of IMR4064. The load is accurate, moderate recoil and effective on whitetail deer. I did extensive research in arriving at this load, both reading and range time. RL-15 is also a good powder, but I have yet to work up a load for it. For a light recoiling target load I shoot a 200-215gr, cast bullet over 15gr. of Unique.
