UPDATE: Well, circumstances didn't allow for actual solid rest - prone position - fire for groups shooting. However, I did have time for 2 boxes worth of informal plinking with my good friend Dopar66. Verdict: My new GSR is a delight; very handy, quick-handling, and it allowed me to nail a water jug at 100 yards [standing, unsupported] on my first try. My shoulder is also quite colorful today, but what the heck....I still really like my new rifle. Thanks for all the helpful responses!
