A mid range Ar1r can be useful to 600. + m with practice
308 /7.62x51 give you more range and availability but if I wasnt worried about ammo availability Id go 300 Win mag my old model 70 with a Leopold mark 3 was deadly as could be out to 800 yards so long as I did my part
Get a good 22 rifle.
A shotgun in 12 gauge
I dont even own one but if I could only have one or two handguns Id probably do glocks in 9mmbig difference in what I would carry for normal concealed carry, urban issues, or heading into the hinterlands
If you have the time a resources to master it a 357 (hwy patrolman/gp100) will do just about anything you could ever need but learning to shoot Ians reload as fast as a semiauto takes time and dedicationId say I burned 10k rounds and 3x a week practice getting to that level
I had a S&W 340PD and would practice with .357 all of the time. Got to be pretty good out to 9yds. Just thinking now the number of rounds isn't good enough and I've never done a speed load.
