A good tang sight is a much needed investment. Personaly I like the 78 style soule tang sight but thats just me I am different. As to your caliber to start with, that is probably the all around best choice you could have made. Brass is plentiful, and easy to find, the choice of bullets will just drive you nuts trying to pick out what one might be the best and that caliber will get things done a looooog way out there.
It will not beat you to death and it is easy to get to shoot well. A good bullet, some good lube and a case full of powder and your good to go.
