Greetings, picking up my first PCP toy, anyone know where I can get my new 4500 psi CF bottle filled around Waldorf or Southern MD? thanks
What is PCP?
Scuba shops AND you local fire department. Most fire departments will fill your tank for a small donation.
That is like asking how much powder do you put in a loaded cartridge. Can be just 2-3 grains for small caliber target loads to many hundreds for a 50BMG. Big bore monsters typ get 2-3 shots before the velocity starts dropping. A regulated target 4.5mm can go a hundred+ shots. Though I would generally say that manufacturers use large enough tanks to get 20-50 consistent shots. Note: you don't ever shoot the tanks empty. You fill, say, 3000psi and need to refill when it gets down to 2300psi. Every gun is different. You have to find (or tune) the max pressure delta that gives repeatable velocity.
