99 percent of the time the Barnes bullet will get more velocity than any other bullet given the same amount of powder. I think it is that Barnes bullets of equal weight are longer than other bullets Thus more bearing surface area. If you can clean out the copper ok then I would go with the X bullet. You can get the penetration you want with a lighter bullet thus more velocity. The 140 X bullet would do all the game you mentioned. I am going to try the coated X bullets next. There should be less copper fouling. You can't beat the partition either. I have not used the fail safe or the A Frames very much.
