I think I poisoned the other thread so I want to ask for help in this new thread. My Browning Cobra blew up 3 days ago such that I need a bow sooner rather than later.

grains = 630 momentum = 154 effective range = 30 yards

grains = 350 momentum = 100 effective range = 35 yards

I was wrong to decide for others, but I'll ask you decide for me - above is the data for a bow I am thinking of buying. Which of the arrows should I use to end up with a quickly dead deer, especially on bad hits? Above is the momentum delivered at 30 yards. The effective range is that at which the arrow drops 5 inches in 5 yards.

I think that momentum is better for penetration than KE, but it hardly matters, the KE of the heavier arrow is also much higher than tht of the light arrow if you look 30 yards down range.

I'm worried about the penetration on bad hits. I knock a twig on the way to the deer and the shaft is still wobbling on impact. I catch a rib simultaneously with two of four blades and deflect the arrow. I grab the bow on release and hit too far back on a quartering away shot.
