Fellow shooters_ in need of advice.

Gentleman could you please give me your opinions on the use of nitrogen in pcp,s. and any experiences that you may have had.  Thanks everyone for your help. take care   kenritz :grin:

Air is mostly Nitrogen (about 79%) and N2 makes for an excellent substitute gas for air in pcp's.  It has the advantages that could be get very dry and it is completely inert, without the associated humidity contents on pumped air and without the oxidation properties of O2 contents in air.  It has being used by many with good success as the propellant gas in pcp's.  Only drawbacks are to obtain the apropriate fittings to transfill an airgun's reservoir from an N2 tank; N2 tanks with the needed working pressure are big, heavy and expensive, although they may be rented; and that most airgun's manufacturers would void warranties if they know about the useage of nitrogen in their guns, but you don't have to tell 'em on the event of a warranty claim.

Add to that a used scuba tank filled at a local dive shop is much cheaper, if you don't own a compressor of your own.  A good hand pump designed for air rifle use isn't all that bad if you're not shooting all the much(most hunting situations).  Lawdog

Thanks mjfa and as usual great advice and just what i wanted to hear. I checked a local weilding supply and it would cost me $38. a year for the tank 488cu.ft. @ 80 to $90 to fill the only problem is regulator @$250. I think it will be worth it.         thanks again buddy    best regards  ken ritz

Thanks lawdog but i have five herniated discs in my neck and back.  also have an implanted pain pump in my abdomin. The nearest dive shop is @ 75 miles away. I would like to hunt but i do all my shooting sitting at a bench rested.  thanks lawdog  take care  kenritz
