Take a trip over to rimfirecentral - you'll find lot's of ideas and help over there as well . . . .
As suggested - put some ammo through it first and get used to it. I bought a standard MK III target last year - I'm not really in to the mods that can be done - I enjoy mine just the way it came out of the box - accurate and have had no problems whatsoever with it. Enjoy the new Ruger!
