I've got a Marlin in 44 mag. I put those XS(I think) ghost ring sights on it and the scout mount. I use a handgun scope, but its not as good as if I would plop down the money for a real scout scope. As far a loads, I dont experiment too much, just a 75% revolver load for plinking. I bought it used and found it had a problem locking up with the lever open. Daignosed it to be a little spring loaded part on what it called the lifter. 35 dollar fix from brownells and smooth sailing from then on. I really love that rifle. I dont have a 44 mag revolver yet, buit like the idea of a pistol and rifle sharing a good cartridge. I dont have a 41mag, but my Dad does...that thing is the loudest pistol I've ever heard...its got one heck of a crack to it..41's dont get enough credit...
