Hi Rhys good to see you back on the forum mate 👍 hope you’re well. As others have said either a hw99 or a hw30. If the the young un is big enough to cock and shoot a 99 I would go for that option as it can be used for hunting if he wants to follow in his dads footsteps as and when he’s able. Also plenty of tuning/stock options to look at as he progresses. Take care mate
