Reply To: 480cc bottle fill with a hand pump ?
Well, only you can answer for certain. But.
You are looking at, very roughly, 1 stroke per cc4800cc + you hose & such + bleed every 50-100 shots to let moisture out + dpressurize hose again……
just over 500 strokes the first time ( but that’s with a gen2 FX pump???).
There after you are just topping off so it wont be as bad and with a regulator you don’t need to fill to 250bar and every shot – on the reg- will be the same fps you will just get fewer shots which might be a good way to go.
PROPER pumping technic will be needed. Stand on pump, lift handle , with your back straight push handle down until you can lock your elbows then just drop all your body weight on it keeping your back straight and your elbows locked, repeat 526 times, LOL.
Keep us posted.
