Great heaps of praised are lavished on the 416 Rigby because it can do the 2400 at very low pressure as compared to the 416 Rem.

Why don't we see the same thing happening with the 458 Lott busting it arse with compressed loads to do 2300 f/s second when the 450 Rigby, 450 Dakota and 460 Wby will do the 2300 with what amounts to reduced loads. The 450 Rigby and Dakota also do away with the belted case of the 458 Lott

Ditto for the 375 H&H Vs the 375 RUM and 378 Wby with reduced loads. The 375 RUM also does away with the belted case of the H&H
