Re: Some recoil stats for discussion

I don't think the powder charge weight really matters, its the velocity that counts.
Lets see.
Calibre / Bullet Weight in Grains / Bullet Velocity in fps / Powder Weight in Grains / Gun Weight in Pounds
A original cartridge loading.
.404 - 400/2150/85/9 - Recoil Energy of 49 foot pounds, and Recoil Velocity of 19 fps.
Assuming a modern powder with the same powder weight gives a higher velocity.
.404 - 400/2400/85/9 - Recoil Energy of 61 foot pounds, and Recoil Velocity of 21 fps.
Increasing the powder charge increases the recoil energy considerably.
.404 - 400/2400/105/9 - Recoil Energy of 69 foot pounds, and Recoil Velocity of 22 fps.
