Ways to get increased accuracy out of X-shot piston pump?

I love my piston pump.but was wondering some ways to get some increased accuracy out of it... I was not quite sure if better darts or a better BCAR.

I have just noticed after moving past about 25ft darts just tend to stray a bit more.

I love the blaster but I am thinking of getting something that hits a bit harder since most of what I do is just shoot empty soda cans out side 😅🤷
