Re: Difference between 375 H&H and 9.3x74R

Factory loads chrono'd from Merkel 140 23.6" barrel:
286gr CDP (Blaser): 2257 fps - factory stated 2295 fps
286gr Oryx (Norma): 2319 fps - factory stated 2362 fps
293gr TUG (RWS): 2288 fps - factory stated 2278 fps
P.S. Factory stated V0 for TUG 293 in 9.3x74R is 2278fps and for 300gr TUG in .375 H&H is 2590fps - therefore difference of 312 fps. However on 300m 9.3 TUG is suppose to do 1740 fps while .375 TUG is suppose to do 1800 - only 60fps difference remains.
Thanks 93.
Your last comment is interesting, since I assume {???} both the 9,3 and.375 TUG's have similar form {ballistic coefficient} and of course similar but not the same sectional density. Strange the nearly identical speed at 300.
Do you have drop tables for the two?
