THE 44mag rifle is the Marlin 1894. The unicorn 44mag rifle is the Ruger Deerfield carbine.
In the Marlin, I prefer the 44mag over the 30-30, less powder, similar range, and more impact.
Hard to complain about the Hornady 225grn Leverevolution FTX for a factory load. Winchester White Box does just fine on deer too.
Depending upon the rifle, load, and shooter, 200-250yrds is comfortable for the 44mag.
