Terminal performance of 147gr FMJ on hogs?

[tpfdchn]

Got a Florida hog hunt coming up next month. This will be an "eradication effort", we're tasked with eliminating all hogs, regardless of size, from a designated area, in preparation for replanting with native plant species.

I have a near maximum supersonic load with a 147gr GI FMJ bullet, pushed by 17.0gr of W296. Most shots to be taken inside of 30 yds.

Whaddya think the terminal effect on the hogs (piglets to fairly sizeable boars) will be? The objective is of course: instantaneous one-shot kills.

I've got time to work up a new super-hog-killer concoction, but if this one will do the job - why bother???

I'd appreciate feedback from you guys who have actual blood and bone experience with Whisper on hogs, deer, bear, etc.

Thanx,
