Talking out my ass here but......

Meet the requirements of caliber for the intended game. Think about velocity and weight of the projectile as well.

The intended rifle can only be capable of loading 5 rounds total as I recall as well. Meaning any magazine would have to be permanently blocked.(not sure about that) But weapons such as 1917's and 1903's would work with the proper ammunition in 30-06

But I still must ask why (dont own a hunting rifle?)and what weapon you were intending to use?
