Ric, it's doable, but I seriously question if it's worth the trouble for anyone unless they have simply run out of brick walls against which to apply their foreheads.
I did it with near zero neck clearance, a lapped mould that cast a bullet fitting the throat pretty much like a glove per ink scuffs, and used the Loverin design so that there was plenty of room for lead to move as the wide lands cut it. About that, it's a catch-22, one would typically use a long, parallel-nose bore rider with two medium-length driving bands at the rear to ride the lands per 2-groove Springfield, BUT due to hotdog/hallway syndrome you simply can't fit a bullet like that (266673) into a Swedish Mauser's cavernous throat and expect it to come out straight on the other end. I also had to make brass with thick necks, which is a chore unto itself, particularly with maintaining absolutely uniform neck tension. Then there's that twist. Not all that much faster than, say, a 7mm-08 and many others that shoot cast well, but not a lazy, easy-peasey twist rate, either. Your bullets had better be geometrically uniform when they come out the muzzle or they will fly off into the wild blue yonder when pushed to anything above very tame velocities.
To keep from damaging the bullet, I had to use very slow powders, quite a bit of work with alloy, and do the monkey business with shredded poly shotshell buffer as was recommended by some in order to get the burn rate into a consistent pressure zone and extrude the bullet into the rifling with minimum drama. One MOA at 100 yards at 2200 fps/15 ft was as far as I was able to get after a couple of years working on it.
Keeping with the Mother Goose theme of the thread "When Karlina is good, she is very, very good, and when she is bad, she is horrid". That's why I recommend to just make the bullet fit snug in the throat, and stick with Alliant 2400 at about 1600 fps. max.
One of these days when I'm rich, famous, and bored, I'm planning to send off my sporterized M96 and have a modern, 22" barrel put on it with a very tight chamber and relatively short leade, and modern rifling. Oh, and probably a 9" twist if I can get it. I'd just build a Savage 110 but I really like CRF.
