Stevehgraham - as you are getting a new rifle, I would urge you to take Marlin's advice and scrub that bore with a good brush before you ever shoot it. Put an already fired brass in the chamber and "dry fire" it to check the trigger. If it is "gritty", there may be milling residue (shavings or grit) in the trigger and/or barrel. You might try some carb cleaner spray on the trigger assembly if you don't want to break it down that far. After you clean the barrel and dry it out with a couple of dry patches, take a magnifying glass and look at the crown around the end of the barrel. Look for any burrs, nicks, or "abnormal" appearances at the opening of the muzzle. Anything "out of round" or damaged there will play havoc with your points of impact (POI).
If nothing is observed at the crown and the barrel is clean and dry, try standard velocity ammo first from a good rest. Expect the POI of the first 1-3 shots to spread a bit but they should tighten up as the barrel warms up and settles in. Don't fire it too quickly as you don't want the barrel to get "hot" as that may throw off you POI as well.
Good luck!
