thanks Mike that was a good read.I use a scuba tank purchased and filled by the local dive shop for my Morini 162EI air pistol. I got a K valve tank, so I have an adapter to DIN. The scuba air is dry. You can use a hand pump, but it is considerable effort to charge a big air rifle cylinder and the air will not be dry. Here's an article you might find useful: Pilkguns
Lots of different ways to charge PCPs. Last I was in Europe many were using bicycle pumps: https://www.youtube.com/watch?v=D-ulTA5iySk
Not a bicycle pump as these pumps go up to 3000+ psi ...
Some folks will use a scuba tank for filling and a "bicycle-type pump" to top off the cylinders. I still like to put clean, dry air in my expensive Morini, so it's just scuba for me.I should have put "bicycle pump" in quotation marks. Thank you for correcting any confusion.

The Hydro (pressure test) is still required every five years. I dropped off my scuba tank a couple of days ago at my local dive shop. The lady at the shop said it would take a week to get it Hydro tested, inspected and filled. The annual visual inspection isn't a big deal and the local shop does that before filling the tank. Luckily I have time since the first air gun match of the season isn't until Sept. 24th in Columbus, IN. Since my dive shop is convenient to me scuba is the way to go. One other consideration is that the pumps usually have problems once in a while and need to be repaired and the pumps are pricey, IMHO. I've heard that some fire stations have their own compressors to fill tanks and will fill scuba tanks, but I have no first-hand knowledge of that. My scuba tank usually lasts me a few years on one fill and I practice quite a lot. Of course a rifle requires more air than a pistol.I have had a springer for about 15 years and got into the PCP game upon the last NRA show in Louisville. I have a .22 Marauder synthetic and the Benjamin hand pump ordered from the show. If you have the coin and a local shop for fills, SCUBA or PCP specific tanks would be nice. If you have a lot of coin, a box compressor and tanks would be ideal for portability and home-fill convenience. I'm not sure if the rules have changed on hydro testing of tanks but when I dove a couple decades ago, shops wouldn't fill your tanks if not current on testing (within 5 years hydro and annual visual). That is something you'll want to consider when looking at the overall scope of tank ownership along with the distance to a SCUBA shop.
I do feel better about sitting & waiting on the next 20 starlings or house sparrows after doing a bit of work with the hand pump. If I was field hunting, I'd want a small bottle with me or just limit my distance from the truck and pump to coincide with about 18 to 20 shots (3000 psi - 2400 psi).
