What a load of old twaddle!!!
1st point, you say he isn't old enough to use an air rifle, then you correctly say he is, if accompanied by someone over 21, although it will have to be their rifle as he isn't allowed to own one.
2nd point, your s410 has a little recoil because it has a different spring in it??? thought it was a PCP.
3rdly, you then tell the lad That a springer is out of his £300 budget, but he can get a half decent PCP. WRONG. Pcp's are the more expensive rifle generally.
