From sun up to sundown? That's a lot of shootin, I've tried 500 and my arm was shot and the front sight came off of the new to me 35.I wouldn’t have touched it until 1000 pellets have been shot.
When I bought my TX200 in 2013, I shot 750 pellets the first day.
I am just about to buy a AA Pro Sport.
I will shoot 1000 pellets and then may change the spring guide.
