I just ordered a HW75. I read a bunch of reviews and post on forums and became convinced that this was the one for me. I have an Alecto but have never owned a single pump pneumatic. I have always read that one should always leave a little air pressure in the multi pumps during storage. I recently read not to leave the 75 charged for more than 5 minutes.
Can any HW75 owners offer opinions or comments.
i wouldn't leave one charged but 5 minutes, who know
you open and load and close and make a small hole, it may be true or just absurd
well just one SSP will never do so what is next ????
i feed mine RWS R-10's 7 grain or Meisterkugeln in 7 grain
in any case enjoy your new pistol
I have always stored my multi-pumps with one pump. It is claimed to keep contaminants out of the valve. Makes some sense to me. Might be voodoo, might be good practice? I currently own only one, a Dragonfly. It takes a little half-cock technique to get a pump in without cocking the hammer, but it's doable. I have never figured out a way to put a pump into my Daisy 880 without leaving the hammer spring compressed, so it gets stored at ambient pressure. (It's a $25 gun so...)
My SSPs, which include a Daisy 753 and a P17 pistol, are stored at ambient pressure, so theoretically stuff can enter the valve, but I've never had a problem.
FWIW, I store all of my CO2 guns under pressure, but I'm religious about not over-tightening when installing a new cart. I usually back it off a hair until I hear a leak, then tighten JUST enough to seal. I also use a drop of ATF on each new cart.
