My 350L loves 165 gr FTXs for Deer, and 200 gr round nosed gas checked cast boolits for plinking. It nips at the heels of the .35 Rem and .38-55, both proven game getters under 200 yards. Recoil is light, accuracy fantastic.
What will the .400 do better?
.400 diameter bullet vs .356 …
Use of heavier bullets
Just a more powerful round increased dow range energy
That’s about it
But .. recoil will increase … Im not sure how much
I think the 400 will probably be purchased by people that don’t hunt in a restrictive state .. and the 400 will be purchased by me .. 16in -18in barrel boltgun
and a AR platform…. Great hawg , black bear option
Pulled this from a article
“So now comes the question, why the 400 Legend? The demand was definitely there for the 350 Legend, but of course, like many things, it had certain limitations. For those hunters looking for more range with heavier bullet weight options, the 400 Legend does fill a gap. It has more than 25 percent more energy and greater penetration than the 350 Legend, with the energy equivalent to a 450 Bushmaster—but with 20 percent less recoil.'
To me the 400 Legend makes me think of the 375 Winchester
But it bests the 375 Winchester
400L 215 gr Velocity 2,250 Energy 2,416
375W 200 gr Velocity 2,100 Energy 1,958
Also being a pointed bullet more effective downrange
Actually the 400L knocks on the 444M door when the 444 is fired out of a 20 inch ( even out of the 24in barrel)
Winchester produced the 307 , 356 & 375 all higher pressure cartridges developed for the beefed up 94 bigbore
Winchester developed a 400 Winchester.. but was never produced.. another high pressure round for the 94 Bigbore .. which probably would have been the best of the bunch …
