Things I liked:Good craftsmanship, no surprise here.
The Walnut stock looks great and feels good against my face on a cold day, as compare to a synthetic stock.
This gun shoots quieter than my RWS 34 and even quieter than my FWB 601
The Trigger is a Match trigger, light and crisp. I left it the way it came.
I found it very convenient not having to unscrew the air cylinder to charge it. I just insert a charging probe into the air cylinder to fill it with air.
I charged the gun to 200 bars. After 45 shots, the air pressure meter in front of the air cylinder shows 120bar. The yellow zone starts at 100 bars.
Things I would have changed:I wish the wood stock has an adjustable cheek piece, and a rail under the forend of stock so that I can mount a Hand Stop or bipod.
What others should know:I noticed that this barrel is thinner then my old HW100 without barrel shroud, thus I was worry that this gun may not shoot well. It likes JSB Exact Heavy, 5-shot group at 25 meters is 0.15 inch. I shot another 5-shot group, but this time it measure 0.17 inch. This tells me that a heavy thick barrel is not necessary for accuracy. Which leads me to think…Does a heavy barrel guarantee high accuracy? Perhaps a reader here can answer this.
Things I liked:No lead dust, pellets are clean and shinny. Things I would have changed:Less distortion in the shape of the head.
Make then in other head sizes too such as 4.49mm to 4.51mm What others should know:I was looking for the best ammo for my HW100. This ammo produce the worst 5-shot group at 25 yards, average group size 0.7 inch. Once in a while, it shoots a flyer. This should not happen for an expensive ammo like this. Other brand of ammo I used in test were, JSB, Crosman, Beeman, and RWS.
