For hunting then you probably want fairly soft bullets, hardcast bullets perform like FMJ on flesh.
And preferably with hollow-points, although that's not essential with soft lead, just use a big flat meplat to initiate deformation. The blunt bullet may not cycle well in the .308 though. I do own an M94, I don't own a Howa.
In the tube magazine I would stick with a flat meplat at least as large in diameter as the primer, although if you were loading light bullets at very low velocities the recoil would be very low making little risk of tube detonation under recoil. The M94 does allow single-feed though, so you could single-feed with more pointed bullets if you prefer.
When you slug the bores, if they measure the same, then you're in with a chance of using the same bullet in both, but the feed systems are very different. The Howa may require a more pointed bullet to cycle.
As for velocity, it will likely be about the same in both, you're essentially loading the .308 back to be a .30-30. As cast bullet accuracy is rarely as good as jacketed bullets are capable of, you might find it easier to keep the .308 for jacketed loads and just use cast in the .30-30, rather than have two different ". 30-30's".
Potential velocity probably comes down to your specific barrels, and how much they tear the bullet, and how much you mind cleaning your bores. There's nothing preventing you from shooting soft cast bullets at 2500fps just lubed with Alox (I've done it myself), but cleaning the lead out of the bore is a chore. With Alox lube and a bullet of around 10BHN, and large enough to prevent gas cutting, probably around 1600fps I would think is easy, maybe 1800fps. Above that I powdercoat them. The powdercoat forms a jacket, the same as a copper one. With PC and a hard alloy you can probably push them as hard as your jacketed loads.
