break in

Welcome!

Most folks like to put a couple hundred pellets through before they get too serious about sighting in. Cleaning the bore with a pull though and some patches is a good idea too. Check that your stock screws stay snug (they like to vibrate loose) Don't overdo the tightening, snug is good enough. You can compress the wood in the stock or break the screws if you overdo it. (ask me how I know!) Many guns will diesel a bit before the excess oils are burned off-you'll hear a crack and see smoke coming out of the barrel. Just keep shooting it till it stops.

Above all, test different pellets to see what groups best in your gun. JSB, H&N, Crosman Premier, and RWS are some of the better brands. Usually domed pellets will be the most accurate. If your gun came with a scope, chances are it's not too good, but try it anyway. If the gun has open sights, use them first to see how the gun is grouping, once you start getting decent groups you can mount your scope.

Good luck and shoot safely,

Clean out the bore leftovers with a bore snake so that you do not have any material in there and do not diesel. Then buy a ton of cheap ammo and fire it all through. Try a few tins after 200 rounds. If it is a springer practice artillery hold while you do this. At the end of these two things your rifle will be broken in, and sighted!



You might want to place lock-tite on some screws (the blue removable one).
 
What gun are you getting? Just because we like to know these things. 
For your new gun. Clean the barrel. Just run some lightly oiled patches through the barrel until they come clean. Then a few dry patches. Then check to make sure all the screws that hold the stock to the gun are snug/tight. Then go shoot. Your first shots may be loud. Like .22 rimfire loud. There can be leftover oil in the gun that causes dieseling. Your target does not need to be any further than 20 yards. 10 may be even better. Does not mater to me if you use open sights or scope. Just done get upset if you don’t get tight groups. This is the “breaking in” part. It could take 100 pellets or it could take 1000. Every gun is different. And this is where you might as well shoot inexpensive pellets like Crosman Premier. 
Then just shoot. Work on your hold. And have fun.
