I've shoot several deer and one Hawg with 44mg Ruger SBH. All from 30 to 50yds and all one shot kills. 240gr JHPs/ 22.5gr 2400. I have never killed deer with a 44 carbine, mostly cause I never carried one much when I had better choices. Presently have a 1894 and #3 Ruger in 44mg. Both are zeroed for dead on at 60yds and both will shoot under 2" at 100yds. Would feel comfortable out to 125yds and 44 is more than enough for deer. I had not much interest in 44 carbines until they ended up legal in our Ohio deer season for straight case -.38 minimum.
