The big advantage of the PP700S-A is the cost first, The feel and balance second and its accuracy third. Very unusual for the price point is it has a regulator. It is set from the Snowflake factory at about 100 bar. At that pressure I shoot 15gr JSB pellets at around 650 FPS and I get 40 shots per air charge to 200 bar. DO NOT overcharge, you will blow out the tank O rings. Generally almost all will leak because the Chinese O rings are crap. Even Snowflake know this, as it comes with spares. It is single shot so it's slow to reload, but I now use a pellet loader tube and I'm pretty quick reloading it now.
