Thanks so far for the replies.

Is there any given time between shots which would cool the barrel enough for the follow-on shots, to minimize barrel 'damage'. I guestimate of shooting once-twice a month throwing 20 bullets (est. 140-200 shots a year). What is than a good shooting strategy en cleaning strategy to lengthen the barrel life. PS. I'm not a competitive shooter, merely using for hunting purposes and now and then on the practise ground. And here in this country is not easy to get new barrels.
