The 444 is a game killer with cast. I used one to take a big hog last year. I was using the lee 310 grainer, loaded over a slightly compressed load of H 335. Not quite max, but getting close. I shot the hog through a blackberry thicket, hitting it just behind the crease of the shoulder. It broke 3 ribs on the entry side, 5 on the exit side, with an exit hole the size of my fist. The heart was shredded, both lungs exploded, pig DRT. This was from a Handi rifle with the 1 in 20 twist. Bullet (or Boolit) was cast out of wheelweights, 40% stick on, 60% clip on, with a Hornady gas check. It is also a load of fun with cast pistol bullets in the 240-250 grain weights, plain base, with Unique or one of the dots powders. It's like the 45-70, mild to wild in the same package. Bullets are comercially available more cheaply for the 44 cal though. I've used the gummi bear hornady's to shoot 2 deer, not impressed with those at all. Too much jellied meat, animals are no deader than the cast bullets render them. The flex tips are perhaps a bit fragile.
