I don't think there is enough difference in the weight to make all that much difference. While both stocks are relatively straight in the comb, for myself the Nula does feel more comfortable on the bench and off hand than does the Kimber. I have been trying to get a handle on the why for sometime now. While I like Kimbers a lot, there is no doubt for my body shape the Nula is a more comfortable design. Others my feel differently.
I do think the more curved grip of the Nula allows the palm to absorb more recoil than the Kimber, which may account for for what I preceive as less barrel jump. I would think the less one can hold onto a rifle-which corresponds to a straighter grip design-the more tendency there would be for the barrel to jump.
