I've tried those before, I've tried many different brands, and although they are good, they dont shoot to well in my HW90.
Accupel are the most accurate and hard hitting for my gun.
But lately as I'm now a student again I'm finding myself leaning towards the cheaper brands, like Marksman which are only £3.75 for 500.
The best pellets I have ever fired are Crosman Premiers, but they are out of my price range.
£3.75 for marksman pellets i can get them for £2 for 500 and still wouldnt buy them i have half a box if u want them
