First of all, why not?

Secondly, the smaller rounds leave little margin for error when shooting any game. A larger round, less margin for error.

Third, practise, practise, practise. With any round that you are shooting.

Fourth, bullet placement, frequently, and it doses not matter in what particular manner you are hunting, there is little time to place a deliberate shot and the larger the bullet, the greater margin of error in a shot to be taken quickly.

fifthr, they are fun!!
