Get the Dominion x39 hollowpoints from CanadaAmmo. 25 cents a round, and they're kind of hollowpoints in name only, I haven't done any expansion tests, but just looking at them, I wouldn't expect a heck of a lot from them in terms of expansion.
But it will keep it legal in terms of the hunting regs.
Also, check your local (provincial) hunting regs. When you're varminting, doing pest or predator control, a lot of those species qualify as "non-game species" in some provinces, so most of the hunting regs (ammo capacity, minimum calibre, no FMJ, etc. etc. ) go out the window.
