[QUOTE="J E Custom, post: 441430, member: 2736"] There are two kinds of recoil, Recoil energy (Total force backwards) and Recoil velocity (The speed at which the weapon moves backwards ) This is sometimes called "Felt recoil". If you look at the formulas for calculating these types of recoil they do not include the case size or shape. Only the bullet weight,caliber, powder in grains,velocity and the weight of the weapon. Heaver bullets= More recoil, more velocity=more recoil, less weight of weapon= more recoil ,ETC. The only reason to feel a difference between two cartriges of different shapes if all other things are equal is the burn rate of the powder that is used. A faster burn rate that produces the same velocity with the same bullet and weight of rifle will reach peak pressure faster and increase recoil velocity and that might be mistaken for more recoil. It is as Dmci Stated (Newtons law applies). So even if it feels like it recoils more, if everything is the same it doesn't. Felt recoil can be deceiving because even the fit of the stock can change the perceived recoil. Just like if you hold a shotgun tight against your shoulder and fire it then hold it away from your shoulder and it will recoil more because in reality it weights less because you shoulder is not adding any weight to the shotgun like it does when held tight. I hope this helps explain your question. J E CUSTOM [/QUOTE]
