Those will do just fine for a lifetime. Something which is quite a bit of fun is shooting in NRA / CMP matches hosted by local gun clubs so look into those as they are just plain fun and include instruction. Matches like this are more about having a real nice day than score. Should you do this you will want some 2 round clips as for rapid fire sequence you load and shoot two and then insert a standard 8 round clip for a total of 10 rounds fired. The 5 round clips are useful for hunting and I use them when I want to shoot 5 round groups on the range. The rifle can easily be fired single shot and loaded one round at a time.
This is how it is done, slow fire prone position. Note how the shooter loads a single round at a time into the chamber. No clip is used, the round is inserted into the chamber and the bolt allowed to go home.
