Hornady specify 2050fps for the 450/400 on their ammo box, chronographed at 1940fps in my 24" barrel, far short of that specified! (Unless they use a 28" test barrel?)
Only loaded Woodleigh's so far & these only to about 2010fps using 66gn of R15 seem to be the best compromise in my rifle.
This load would be ball park to what a load was 100 years ago in the 3" version, FAR short of the advertised loads - guess nothing has changed in 100+ years in the gun industry!
As to comparing this Savana queen to a modern .416 Rem load, it's well & truly left behind ballistically!
As to which one to take, it wouldn't really matter - all can do the job, I just wish I could get there!
