Are you required to use expanding bullets? What type of game?
In most cases, the typical bullets will not expand nor be ethical hunting bullets at SubSonic velocities. Unfortunately, lots of people have figured this out the hard way with lots of game needlessly suffering. The SMKs mentioned above fit in that category. That is why most people end up going with SuperSonic loads for hunting.
The bullets that do expand at SubSonic are very expensive. But there are also a lot of people talking about the "modern 30-30" and hunting who have no real world understanding or experience. If you will search, you can find several people disappointed in the round with SubSonic performance on game.
