Max shots at optimal velocity vs max shots per fill?

[Kavliaris]

Hello everyone... I am thinking of buying a Hatsan Blitz .25 (or .30 I am not sure yet). The main reason I want it is because I will be filling it with hand pump so in comparison with other pcps where they shoot 20-30 shots per fill this pcp with 100+ shots seems to be ideal. (It also has decent power for its price). I saw that Hatsan says the Blitz shoots around 100+ shots at *optimal velocity*.... And my question is... How many decent shots could it shoot after the first 100 optimal shots? Lets say the first 100 have around ±700 fps... How many more shots until it reaches for example 600 fps or 550? Or it doesnt work like that? And lets say I only shoot the 100 optimal velocity ones... How much air would be left in the tank? How many pumps would I need to fill the rifles tank back to max in comparison to the tank being completely empty? I am new in pcps and english is not my main language so I am a little bit confused. I hope someone can explain to me... Thank you

When I checked out a bliltz 30 it was getting over 746 fps with 44gr pellets I tried turning hammer spring tighter but it did not adjust like other guns do in my opinion I'd get a different bottle gun I believe they are a 480 to 500 cc bottle on them and Benjamin or crossman have a couple different options which would probably be more user adjustable

Probably another 10-15 shots before it completely falls off. But that is just an educated guess on my part. You can always throw a 700cc bottle on it and extend the “optimal shot” range.

lots and lots and lots and lots and lots of pumps times infinity.

No way I'd ever buy a full auto that had to be handpumped personally especially a Bottle gun. I've handpumped 500cc bottles to 250bar. Takes hours since you have to let the pump cool back down every 5 minutes or so. I know how I'd shoot with a Blitz and it wouldn't work well for me. Filling longer than shooting gets old. If you want a high shot count 25/30 with decent power they are out there. For the same price you can get a .30 sidelever that gets 40shots a fill at way more power and a portable compressor that will still give you more time shooting.
