Thanks for the help. I think I will just go with the 435gr. Most elk should be under 100yds. The farthest shot will be 100yds but should be around 80tds. You do not need to push these things really hard to make them work. 100 grains of Goex FFG will do more than get it done. Even 70gr would get it done. My 425gr Hornady's like 100grns so the Buffalo Bullets might to.
