I have a Vz24 action with a 7x547 military barrel on it, cut down to 24". It shoots 140-grain bullets very well. Haven't tried any other bullet weights. I use the loads in the Nosler manual, which IIRC are limited to 46,000CUP to be compatible with the older Mausers.
Recoil is light - I sure wouldn't mess around with a BOSS, ports or a muzzle brake.
Often the muzzle on older military barrels is worn from cleaning, so cuttting it down to 24" and recrowning may improve your accuracy. I just duracoated my 7x57 and am extremely pleased with the appearance.
Godd luck!
