Way back in 1905 was a 7mm (.287) Magnum that reached 2900 fps with a 150 gr bullet !
It was a Canadian invention called the 280 Ross.
In 1910 the M 10 came out. Recently I bought two rifles, both 1910s. I'm keeping the 28" barreled Highland Stalking Rifle.
Happily C&H makes dies and cases are available from Buffalo Arms. Woodleigh maks 2 weights of .287 bullets.
Cases can be made from 375 Ruger but they are almost as expensive as the Buffalo Arms ones (made from 50-110).
After a lot of figuring, I found that the 280 Ross can be loaded with 7mm RemMag starting loads.
You can load .284 bullets but in my less than perfect bore, they about double group size. So far I'm gettin 3 shot 1" groups @50 yards with the .287 bullets which, considering the cordite and corrosive primer abused bore is amazing.
Of you have one, get it shooting again.
