Cast bullets are easier on your barrel. Veral Smith revolutionized hard-cast bullets for hunting when he created Lead Bullet Technolgy ("LBT") which is the style of most of most of the bullets sold by by the owner of this site - Beartooth Bullets. The idea is a wide/flat "meplat" (nose) that crushes its way through the target and does not expand. You get awesome penetration with devestating results especially with "pre-expanded" large caliber bullets like the .44 mag. When LBT bullets first came out hunters were claiming that "hot" LBT handgun bullets in the .44 mag/.45 Colt range would kill on a par with .300 mag rifle. It started a debate and the high velocity expanding bullet crowd could or would not believe it. Same principle as large solids on dangerous game in Africa except with a big flat nose. Since then, the LBT bullet has proved itself without a doubt. You can shoot highest power loads in your .44 mag with gas checks and not lead-up your barrel. Even without gas checks you could shoot up to around 1,200 fps. So let's say you got some 325 grain Wide Long Nose (WLN) gas checked hard-cast bullets from Beartooth Bullets and drove them to 1,600 fps with "only" 1,700 foot pounds of "energy" you could shoot through any game animal on earth broadside and shoot end to end on a large bear. Penetration would be up to six feet. A .300 mag, or just about any expanding rifle caliber, even a .375 H&H or greater with 3,000 or 4,000 foot pounds of "energy" would provide much less penetration probably about half if the bullet expands as designed. Even at 1,200 fps your 325 grain LBT WLN will shoot through just about any critter you will ever find. I love LBT hard-cast bullets and the Beartooth bullets are as good as or better than any you can find anywhere. You can even buy LBT molds from the man, Veral Smith, and cast your own.
