MOntana Precision Swaging can produce 350 grain paper patch bullets for the .444, but I don't know if they will stabilize at that length. Would be about an inch long +/- a few thou. 300 grain bullets from the same die run .86" and work fine in a 1:20 twist. All I know so far is they'll go thru a hog shoulder and stop on the off side ham. About 22-23". Harder alloy than dead soft I shoot would likely work better for bear.
