Myself, I think wood contact with all points on the receiver is critical for preventing recoil caused cracks. I also think proper removal of the butt stock is critical for preventing cracks. And I also think not ever dropping the rifle is critical for not causing cracks.
Who knows what the causes are for all Savage cracks, but if I were a betting man I'd say 98% percent come from bad stock fitting, bad stock removing, and from dropping the rifle. Oh yeah, wood too is a non-consistent medium subject to weaknesses and failures all in itself.
