Hi fella, it is good discipline to wipe your gun down after every shoot and will keep it in tip top condition, i would oil only the working part's that need it, but only a little at a time, it takes only a very thin layer to do the job, clean barrel only when accuracy start's to tail off, some barrel's are more fussy than other's and rarely need a clean, but if rifle get's very damp then a pull through with a little oil on a patch and then a dry patch pulled through will clean it really well and remove any dampness then a few of your favourite pellets to relead the barrel and job done. people
