The .450/400 I listed as doing 2050 fps which is common. I would need to look up some published velocities but if it was increased to 2150 fps there would be an increase in recoil of course. If it is compared to the .375 in the first post, it is milder. Interesting to see how velocity affects recoil. I will play around with those numbers some more.

The old .404 used to shoot a 400 gr projectile at around 2150 fps as well, so those sorts of ballistics are effective on game. With modern loadings the velocity might be more like 2300 to 2400 fps. With greater recoil.

Rockdoc,

I actually think a lot of rifles are heavier than listed. The catalogues often show a weight with the real rifles actually being heavier.

The "light" .458 Lott I included as I recently read such a comment elsewhere "I prefer mine to be 8 1/2 lbs total weight, I have no problem with the recoil and can shoot it all day ... " or some such tripe. Sometimes there is a lot of this sort of BS on the net. If such a rifle exists, it is a mistake IMO.

Will have to do the numbers also for the .577, .600 and .700, plus the .460 Wby. The .460 Wby Mag is a favourite until guys actually buy one, and then try to shoot it, so easier to get cheaper ones second hand.

I find recoil is a progressive thing. My experience anyway. To go from a .222 to a .450 NE would not be a good idea, but my progression was .222 to .30-06, to .375 H&H to .450 NE and then larger. With each step the previous one started to feel "softer" compared to the newer bigger one.
