When I return to Zimbabwe in March of 2006 I will use North Fork Cup Points in my 450 No2 on buff. Probably the 450 grain, unless he makes some 500 grainers, I would have to thes them and see how they shoot. The 450,s shoot pretty good and the velocity out of my double is 2240 fps with 90 grains of RL 15. With 89 grains it is 2205fps. I am not sure which load is best as I have not shot them at 100 yards yet.
