Nice looking stock and accuracy seems great. You are setting a standard the rest of us are struggling to meet. But I am confused by one thing in the giveaway - this is a .25 caliber gun but the giveaway includes .22 pellets?
I would not mind winning the .22 pellets with the .25 gun - I have a .22 Gamo Swarm so could use them... of course the kind of accuracy the S510 XS implies would be so much nicer than what I am getting now... ok, it could be the shooter...
