Good advice above. I've taken somewhere around 40 deer with the 41 magnum in 5 different states, all with cast bullets. Barrel length is up to you but I like 5" barrels for the most part. The 44 & 45 are just as good or better, it all depends on good bullets & shot placement. The 357 works just fine out to 50 yds or so, again with correct bullets but you have to be very careful with shot placement but it will work. Good luck.
