30-30
I have a Ruger Deerfield and really love it, the nice thing about the Ruger 44mag rifles is they all take the same rotary magazine no more shuking all the rounds through the chamber to unload.
The 44mag in a rifle is devastating at close range(125yds) and with the right bullet i wouldnt hesitate to shoot an elk. I have been using Speer 270gr gold dot factory loads and they perform very well. 290 bucks is a good deal if the rifle is in good shape, i paid close to 550 for my deerfield, and those scope rings are awesome no scope bases they attach right to the receiver like all Ruger rifles. Good luck
