I went and sighted in my Remington 700 adl in .270 on Sunday. ...But I fired another 5 shot group at 50 yards and every other shot was to the right, 3 dead center and 2 about 1/4" right. Is it possible that I need to break in the barrel or was that just my shooting?
The Remington ADL is a hunting rifle. From your description, it sounds like it's shooting just fine. 3 shots dead center and 2 shots 1/4" right is perfectly acceptable for a hunting rifle at 50 yards. It sounds to me like it's shooting pretty close to MOA. I'd move my target out to 100 yards and see how it shoots.
You might want to check to make sure screws are tight and try to bed it to the sandbags the same way each time. As your target moves further from the rifle, small inconsistencies in forearm pressure, cheek weld and trigger control will start to manifest in ways that will make your group open up.
All the other stuff folks recommended (upgrade mounts, rings, scope, bed the rifle, trigger job, etc) are fine to do as you are able to do them, but from the description, it sounds like you should learn your rifle before you start making changes.
