I have a question about negative comb. Some custom LR stocks advertise needing a negative comb to prevent the stock from smacking your cheek. However, I was reading about McMillan's BR stocks that have a very small drop at the heel to allow the comb to drop away from the face, even with a flat comb. It makes sense to me. If the heel was flat, I see the negative comb being advantageous.
I have a monte carlo and a McMillan A3 which has a flat comb and I don't get cheek slapped be either, even in larger cartridges. My shotgun is a different story.
