The problem with the 6.5MS in Great Britain is that it is not deer legal as the velocity with the 160 grain bullet is insufficient. It WAS until that law was introduced very poipular as a hill stalking weapon. Light, low recoil, and with the 160 grain bullet, apparently, a good killer on red deer.

Would I consider an old Mannlicher rifle nowadays? No! You will struggle to get the ammunition and I don't think that it has the flexibility of the 6.5 x 55 or other more useful cartridges in that size.

Also some of those old Mannlicher rifles are a bit generous on the bore dimensions and not given to modern accuracy standards...especially if they have been shot with a large quantity of cordite loads in the past.
