Loads are really best assessed by each individual and the gun. Ask 10 ML's what the best load is my bets are you'll get at least 7 different answers.

My best load and what I have used to take 4 animals (3 deer and 1 Black Bear) is; Hornady 44 Cal, 240 Gr XTP Sabots with 100 Gr of Pryodex Pellets. I shoot 1-11/4' groups at 100 are my norm. With all animals meat damage was nill, in through the ribs out through the ribs...longest shot was 125 yards, closest was 45. If meat is a concern don't ever shoot the animal in the shoulder, if the shot is not their don't take it.

As far as scope and cleaning. I flush my barrel with hot soapy water, using a funnel, into a icecream pail. Then follow up with hot water and clean patches. I wash down all exterior parts with Hot soapy water and soft dry cloth. Final prep is apply a layer of rem oil with a soft cloth. I use tooth brush or the likes to clean out the rings and breech area. When I shot at the range, I will tape the scope in the breech area to elimate blast, while hunting one or two shot will lightly flim the scope base and easily wipes away when cleaning. With heavy fouling it may take me 45 minutes from start to finish, light 20 minutes...but i am real particular as well.
