Fellow southpaw here.
I also like to dump hogs whenever I get a chance to. TX and OK.
Since you are a lefty, I suggest that you handle an M1A Scout, LRB Arms M14SA Tanker, or a Fulton Armory M14S Tanker.
The above bbl lengths are 18, 18.5, and 18.5 resepctively.
Caliber is 308, and 7.62x51mm.
Weight can vary depending on how you like your's set up, but land between 7.8 to 8.8 lbs there abouts.
OAL varies depending on what type of flash hider arrangement you like, but between 37 to 40 inches.
Mag capacity starts out at 5rd, and works it's way up to 20/25rd.
Being a left handed shooter, you may like how the M14 types are laid out.
Safety sits just like an M1 Garand, op-rod handle is easy to reach with right hand, along with the mag release, and the left hand never has to move from it's firing position. Them right handed folks were so busy trying to make it a right handed rifle, they screwed up and made it more lefty freindly....(lol)
As of now, I'm out of TX due to work, but have managed to dump 200 plus hogs with my hog slayin M14S.
Most of my shots have been inside of 100M, and my longest lasered hit/dump was at 396M. I personally have never even seen a 1000+ lbs hog, but they might be out there. The piggies around here are typically 200lbs and less.
FWIW...... The little ones are better for eating in my experience.
With that being said, I am also fond of 7mm08, but havent found enough difference between it and 308 to justify spending funds on a different rifle and ammo to make the jump.
My M14S and M1A-A1 aint going anywheres regardless, and them Ruger GSR lefty rifles look pretty nice, if you would rather use a bolt gun.
Us lefties gotta look out for one another.
