awmp...............brush, open flat lands, timber, swamp,.....what?
In any case, the Mini 30 will be your best bet. Next time take your new 6.8spc that you bought before telling the laughing no gun appreciating wife.
Semi-autos are best...........otherwise you only get one pig. When they start bouncing and heading for cover....a semi-auto will get you one or two more------IF YOU SHOOT WELL.
A red or green dot sight or recticle works best as the action is fast and over quick. Most shooting will be at less than 100 yards.
Leave your Glock in the car for travel protection. You won't be going after a 400 lb boar in the thick brush. Most will be 60 to 100 pounders.
If you have a variable scope put it on lowest setting.
Btw...........the people taking you hunting........have they been before? What are they telling you?
OH yeah.......be sure to dress out like a SEAL going after jihadist terrorist cell. Otherwise the hogs will snicker and laugh at you....
