mrat my old friend, good to see you find your way to the promised land of S/A revolvers.
As already mentioned, the big difference between the .44Mag and the .45LC is all in the loading,,as in handloading. I own offerings in both calibers and would be hard pressed to pick a favorite. If I did have to choose, I believe I'd go with the .44Mag. The reason is pretty simple. The .44Mag is just my favorite all around, do everything be everything caliber. Since i do handload, the basic difference to me is all in the brass. .44Mag brass is a more *modern* design, and will feed through more platforms than the .45LC. The larger rim of the .44Mag case will function through a revolver, lever action rifle and semi auto carbine or pistol.
You do understand that the next step or bug to bite is a lever gun right ? The bigger rim also allows more purchase for the reloading die to grab and lessens the chance of a torn-rim-stuck-in-the-die case.( a very small probability I admit, but still a factor when pushing the .45LC to it's extreme limits). Loading data for the .44Mag covers a wider range of velocity and bullet weights also. W/.45LC, it's basicly 250-255 gr.
Bottom line is that both are so close, in the strong action of a Ruger, it's a win/win situation.
I guess it boils down to are you the variety type,,in which case since you already have a .44, the .45LC would be a better fit,,,or are you the stay with what I know and like type,,in which case the .44Mag would be a better fit. I'm a little of both and a little of neither myself. (being a bit of a purist myself)-->My goal is to one day buy a .45
Colt, with Colt being the operative word,,as in Colt Single Action Army,,or Model P<--the real deal. That means I'd prefer to leave Mr. Murphy out of the loop and lessen the chance that a Ruger only hot .45LC load ends up in it. That usually draws me to the .44Mag,,,then I catch sight of that big 'ole hole in the end of the .45LC (why is it the .45 just LOOKS so much bigger?!?)and the indecision sets in all over again.
*sigh* {{big wants/little paycheck}}
. Whichever way you go old friend,,
1.) Let us know how it shoots.
2.) Give some serious though to reloading. Reloading is the only way to really turn these cannons into plinkers.
