i do not "hunt", so these are for other situations....
pistol: i have a cz97b...45acp 10 rds, plenty of mags....lol even legal in kalifornicating state.... alternate is my cz85 in 9x21....135's at "nice velocities".....ok i can easily do 1300 fps. 25+1 rounds.
shotgun moss 590 8 plus one with 9 more on the stock
rifle.....ar 10t......20 and 25 rd mags....24" bbl, i can hit the 600 yd x ring prone...(moa).
lots of various ammo as discussed by others. try the hornady 130 spire point. hits the lands from mag length ammo and shoots sub moa.
i agree lots of other rifles are good choice, but limited fire power.. most of my mil surplus scoped rifles will work at longer distances than production ar15's.
