Krieghoff - .500/.416

I remember reading on the net that actual users found that velocity a little 'optimistic'. Perhaps any members who have chronographed one could share?

Lets assume:

10 lb double rifle
.500/.416
410 gr bullet
105grs powder charge (high side)
Velocity 2330 ft/sec

Recoil Energy of 61 foot pounds, and Recoil Velocity of 20 fps

10 lb double rifle
.500/.416
410 gr bullet
100grs powder charge
Velocity 2200 ft/sec

Recoil Energy of 52 foot pounds, and Recoil Velocity of 18 fps

A .450/.400 3"

10 lb double rifle
.450/.400 3"
400 gr bullet
72grs powder charge
Velocity 2100 ft/sec

Recoil Energy of 39 foot pounds, and Recoil Velocity of 16 fps.

OK makes sense. I believe you have posted again but I haven't seen that last post yet.
