Welcome to the CPC. This is a great place and you'll find alot of information here.The Benjamin Discovery is a great first PCP and a good choice. Most who shoot them use the 15.9 grain JSB Exact pellets. The H & N Sport Field Target Trophy 14.66 grain pellets in 5.53 diameter head size also shoot well in the Discovery from my experience. Keep in mind that using the Discovery filled to a starting pressure of 2000 PSI you will get around (20) shots that will give you a good power curve and your ending PSI will be around 1200PSI. My personal .22 Discovery using the Field Target Trophy pellets starts around 819FPS and peaks around 844FPS and at the 20th shot I'm back down to 818FPS. That's a great power curve for a PCP in the price range these Discovery's are.As far as an accuracy prep, I'm not sure it that is totally necessary, however, if you are new to PCP's or air guns in general, then it can get you shooting accurately much faster. If you run a few dry patches down the barrel to clean out the oil and metal gunk that is in the barrel from the factory it should shoot pretty good. Probably the most important thing is using the right pellets. Find the one that is the most accurate and stick with that one. The ones I mentioned above typically work well in almost every Discovery.You can get scope rings from almost any place on the web. Depending on the bell size on your scope you'll either need medium or high scope rings with the 11mm/ 3/8" dovetail type of attachment. If the scope bell is 40mm you could probably use medium, but I personally use high scope rings on mine. If the bell on your scope is 50mm then you will definitely need the high scope rings.There is a mod you can do to the trigger (two screw or three screw depending on which you want, I did the two screw mod) which will take some of the creep and overtravel out of the trigger. You can look up how to do it up on YouTube under "Discovery Trigger Mod".Besides doing the trigger mod, the only other thing I did was I purchased a stock from Boyd's Gunstock Industries. I got the unilet Ross Thumbhole Sporter Stock and I inlet myself for the Discovery because I wasn't crazy abou the Disco stock. But the Disco stock is nice and light, so that is a plus.If you want to use a rifle sling on it, you'll want to either get the Gamo Sling Buddy, which will attach to air guns without sling studs, or you'll want to purchase some sling studs and install them yourself. The Discovery doesn't come with sling studs.If you want to learn alot about PCP's and shooting them, I would recommend you look up "Ted's Holdover" on YouTube. He talks about holdover/holdunder, pellet speed and chronographing for accuracy using the mildot scope system and much more. If you have questions, feel free to ask. If we know the answer we'll let you know and if not, we'll say so.Once again, welcome and have fun with that air rifle.
