First off, despite what even the experts like Troy say (believe me, no disrespect meant) I don't believe fragmenting bullets will "spoil" meat. I suppose it depends on the size of your quarry and where you are shooting them but people do kill deer with the OTM, BTHP's whatever you want to call them. And they work. With deer, if you put one in the body, it will not throw framents out to the legs and ruin the meat. it will typically stay inside the body cavity. Now, it may ruin the inside tenderloins, but even that is not a given.
Javelina are usually smalller I think, so this may be different for them.
AR15kittykat had exclusively used Q3131A for boar hunting and killed lots of them with cool pictures and it fragmented. And he still ate them.
These types of bullets may be illegal for hunting purposes, check your regulations. And colt100, the regs for Deer and Bear state you need to use bullets that are designed to expand but, last year I did not see that wording anywhere in the small game book. I challenge you to find it. If so, I stand corrected. I know Photoman said he checked with his local DNR guy, but if a guy don't see it in the regs, how would he know? And what is the logic behind that? You're telling me you need an "expanding" bullet to hunt rabbits? And some guys shoot small game with .22's and most of them bullets aren't made to expand. My point is that even though some say it may be illegal, I'd like to see it in writing for small game.
I would say the 64's are a good choice though.
