Being as the m99 ends up being ammo starved at times due to availability I got to looking.
ableammo.com it appears there is some 416 caliber bullets available in a variety of weights.
Has anyone loaded any of these before?

I will also add in I am jealous of the 50 cal owners who obviously dont have as much trouble finding ammo. Also some 50 cal ammo new in box is approx $2 per round instead of the $5 per round the 416 owners encounter with no alternatives.
