I'd be curious what folks would suggest for a more economical and accurate alternative for fast short range shots on deer and hogs in areas with lots of cover. AR?
Yes an AR in .350 L or .450 BM would be where I'd look first if you want a semi auto.
I would go AR as well. I looked into the Ruger 77/44 a while back but saw plenty of accuracy complaints as well. I know a guy with a Thompson,I forget the model (the light weight one) single shot 44 mag with 16" barrel. He showed me a 100 yard target with 5 in less than an inch. It did shoot like crap though with the first ammo he tried. He says it weighs less than 5 lbs.
