:cb2: Hey sigep538. Glad to have ya here at GBO.
Like Ricky said, each handgun is different as to what it likes. You could take two Ruger Blackhawks that came off the line, one right after the other, and they would shoot differently. One might shoot 240-gr. Winchester Silvertips the best, the other might shoot 240-gr. PMC SP the best. Both may or may not like the Federal 300-gr. CastCores, etc., etc., etc. It's just gonna take a lot of trial and error to find what shoots best. Talk to the guy you bought it from and ask him what he used. (Of course he may not have found a good load, and that's why he sold it thinking something was wrong with it.) Once you find your "serious business" load, keep a box on hand, and then get some cheap reloads and have a good time with it!
As for the scope, make sure everything is really tight. Ya sure can't have any wiggle anywhere. I took my regular scope off of mine, and put a red dot scope on it. Still not sure I did the right thing. Only time, and practice, will tell.
Again, like Ricky said, try it without the scope, too. You might like it better. (Depends a lot on how old you are, and how good you can still see!)
You mught also want to get some ear plugs at the drug store (usually cheaper there) and wear them along with your muffs. Your hearing is too valuable to lose, so use both!
The .44 mag is the most fun gun to shoot of all. Especially a single action. I prefer the Bisley grip, but you can't really go wrong with a good ole Blackhawk.
I'm glad you found GBO. There are a lot of guys here, tons smarter than me, and I'm sure you're gonna get some great pointers and advise. Good shootin'!
