It's not cost effective to load jacketed rounds, no (unless you are loading soft-point bullets, in which case there is a modest savings over brass cased ammo, but break even against steel cased).
If you cast your own bullets, however, it's a whole other ballpark. Having said that, you probably aren't interested in shooting cast lead subsonic gallery loads or even mid-range gas-checked target loads in that semi-auto. For the mosins, however, loading your own is the only way to go for the truly CHEAP (like me).
