How does bow design affect impact point?

[Red Dwarf]

I do most of my shooting with a 48# Caribow "Wolverine" R/D longbow.
The other bow that I shoot from time to time is a beautiful 57# Bear with a "B" wood riser T/D & no. 3 limbs.
For some reason, although the Bear is 9# heavier, it shoots the same arrows about 4" lower than the Caribow at 10yds (My basement).
The knocking points on both bows are very similar, being approx. 1/2".
What would cause this to happen?

Red Dwarf.

p.s. Although I do not have a chrony. the Bear seems to be a bit quicker.

The arrow shelf may be cut diffrent.Some are cut closer to the hand.

I had some 57# Bear limbs and they always seemed "doggie".I didn't ever get a chance to chronograph them but my other bows,50-53# seemed to out penetrate them and shoot flatter.I had a set of Rose Oak limbs built for it,in a 51# weight and they changed the personality of this bow.Seems faster,definitely quieter.I sold all 3 pairs of Bear limbs after that.They all shot well but I felt performance was lacking. I like the Rose Oaks so much better.

A different grip may cause different hand placement, which would also cause different arm placement and would result in different arrow placement.

Thanks for the input guys.

I will play around with bow hand placement and see what I can come up with.
