Wife had good success using a Ruger Semi-auto Carbine in 44 magnum. She got a large Feral Hog and a Whitetail Doe on our September trip. She used Mag-Tech 240 grain SJSP ammo.
I just got a new Ruger Model 77 Bolt Action in 44 magnum. I will be using the same ammo as "The Boss". I hate to set my Winchester 100 (.308) aside, but the ammo is not legal for hunting in Indiana, so the 44 magnum will step in. The Saiga 12 ga will go back in the rack too. No more slug-gun shoulders for me.
