Camba: that is a good thought for the 45. If you are into casting, may I recommend the old Lyman 452423 slug, a 238 gn Keith style semi-wadcutter that usually drops out at 240-250 gns, works great (was designed for) the 45 Auto Rim and the 45 Colt, and shoots very accurately to poa from my 45 acp. I prefer this slug, over 6.7 of Unique or 6.5 of 231 for somewhere between 875- 900'/sec for Whitetail, if they are foolish enough to come within 50 yds. If you do not cast your own, both Colorado Cast Bullets and Mt. Baldy Cast Bullets cast these slugs.
