I have a sporterized, '03, Rock Island rifle. I am considering loaning it to a colleague who wants to hunt pigs in TX (I assume over bait).

The rifle has the original arsenal barrel on it.

Were I to be wanting to hunt this rifle, I would buy a custom mould for it and use a flat-nosed, gas-checked bullet of some sort for that job. And I may yet do that. But I'm unlikely to ever hunt a bolt rifle so I wondering if there is an off-the-shelf ammo, undoubtedly copper jacketed, that would be sufficient for this purpose and safe in this rifle. Could anyone make a recommendation or two or are there none?

Thanks,
Brent
