Deadeye 1: You are right, stock configuration is big on the list of what influences felt recoil. The calculations will tell you how much backward thrust a certain cartridge with a certain weight bullet with a standard factory load in a particular weight rifle will produce, but a well-designed stock with greatly influence how you feel that thrust.
Shooters should be aware of all the factors that go into kick:
1. stock configuration - small drop at comb will direct the kick straight back, and is normally more comfortable.
2. recoil pad vs hard buttplate - plus the size, angle and shape of the buttplate determines how the butt of the rifle digs into your shoulder (some of those old Winchester lever actions with the curved metal buttplate kicked like the dickens!).
3. cheek piece - Weatherby rifles are well-known for having a large cheek piece on the stock, which allows the face to slide smoothly forward when the gun is fired without getting your face slapped.
4. weight of rifle - you can reduce kick of your rifle just by adding some lead to the stock. Modern lightweight rifles will always kick more than the old, wood stock 8 lb+ rifles, all else equal.
5. weight of bullet - lighter bullet, less kick
6. weight of powder - fewer grains of powder, less kick - if you switch to a powder that requires fewer grains to generate the same pressures, you'll get the same velocity with less recoil.
7. speed of bullet - reduce your load just a bit, and you get a twofer: less kick from a slightly slower speed bullet, and less kick from fewer grains of powder.
