If you want, swing for the fences, but there's nothing wrong with factory class. There's nothing wrong with open, just depends on what you want to do
You're still on the same line as everyone else firing the same sequence of shots. There's no difference.
Keep in mind there's A LOT of other equipment your going to be buying. Most people have tripods, spotting scope or binoculars, range finder, several different types of shooting bags, bipod, kestrel, and various other small items. Do you need most of these items, no, but some you do. Bipod and one bag is a must.
However with the exception of the bipod there is usually a handful of people that are happy to loan a bag, offer the use of a spotting scope, and other items. So you don't need them right away, but eventually you will fill out your equipment to go along with the rifle/scope.
O and for the luve of donuts, make sure you grab a scope with a zero stop. I didn't, and that screwed my day.
