Kind of what I was thinking between 270 and 280ai
should have prefaced I have:
450 nitro
375hh
300wm
7mm rem mag
I wasn’t trying to get suggestions about how to fill the gap.
Just curious on opinions on what cartridge we think fits the bill.
Was thinking North America.
I know 500 isn't long-range for some of you but due to my ability, it's my self imposed a limit for shooting game.
The best combination of rifle portability, power, trajectory, reloading components and or ammo selection.
If you pm me your email I will send you load info for both. I highly recommend you get the book “ shooting the British double rifle “

There is allot going on for loading doubles especially vintage ones.
