I've shot one hog at 30 yards with the 270gr Speer in the .44, shooting a Ruger #1 - it was DRT. The same Ruger has been kinda fussy about accuracy, and 1¾-2" groups is about the best I can do at 100 yards. The one .30-30 I have, a Contender Carbine, also worked well on a doe, and is a good deal more accurate.
Other than a wornout lever gun, I would think the .30-30 would be more accurate and have a better trajectory than the .44 mag. I have not yet given up working on mine, however.
