Yes you did. You have to add the weight of the burnt BP or eject-ta. Burnt smokeless has far less weight to it and is used in much smaller amounts. Bp has a much more noticeable kick than a Nitro for Black load. Also burn time affects felt recoil. Bp burns slower so it pushes against you longer. That's why some people say Bp firearms have more of a shove than a kick. I am fairly sure this will start a friendly discussion.
