Just a click slower than a 308 Winchester
I have just done a ballistic table for it and it has enough velocity and energy to be ethical to 500m for my hunting style.
Like your 270 7x64 comparison the 30-40 should out perform the practically identical 303 British, due to the 1:10" barrel twist and better bullet selection

My .30-40 Martini will be putting in an appearance on the 300 yard mound for F-Class this year. The barrel has a 12 inch twist so will likely use a 165 grain projectile, 168 grain maybe. A 131 year old cartridge in a 142 year old action rings my bell.
GPM.
PS I have had the rifle since the late 1970's and it was rebarrelled to .30-30 in 1981.
