I shoot laser cast 405 grn,  and  aardvark 405 cast,  my loads are
  40 grns of IMR3031 for the laser cast  cci 200 primers, win brass
  for the 405 aardvark bullets  I use 38.5 grns of 3031 same primers
  and brass.
  I've read that guys  do take it up a bit ,  but  I took my blacktail
  with the laser cast,  I was rally impressed with the  thumping
  it did to a 130 lb deer.  I wouldn't  hesitate to use it on Elk at under
  150 yards.   these loads are about the most accurate I came up with.
  Laser cast list the Max load for their 405 grn bullets is 38.5 of IMR 3031.
