Looking for a subsistence hunter myself.
I settled on PCP, because with repair kits for the pump and the rifle I should be able to keep them working for a good while.
Many of the airguns are made to satisfy the desire for a "real" rifle in places where civilians can't own "real"rifles. I don't need a wood stock or any more shroud or weight than is necessary.
I have a Marauder that is wearing a plastic stock.
The Marauder is the best that I own. I paid $250 for the rifle and $40 for the stock.(Not drop-in)
The Marauder is also the heaviest. It has a large air tube rated @ 3,000psi working pressure.
I have the Disco that is pictured on page 2 of this thread.
I bought the tube, breech and shroud for $250 and spent another $50 on trigger group and stock
The Disco has an after market breech that takes Marauder magazines. (10 round bolt-action)
The Disco has a stainless steel tube that has a higher pressure rating than the MRod
I have a 2400KT that I got from Crossman Custom.
About $130 with shipping. Includes steel breech, Prod trigger group, and stock.
$75 plus shipping for a Hi-Pac tube makes this a PCP.
I have a 2540 because I ordered a .25 barrel to put on the Disco.
The .25 barrel didn't fit the BNM breech, but it did fit the Crosman steel breech.
A basic 2240 plus a stock, a TKO shroud, and a Hi-Pac tube make it a PCP for $245
I got a $30 CO2 can and a Disco charger from Sports Authority where they charge the can for $3
I have charged all of the rifles twice and the can is not empty.
I just bought a Benjamin PCP pump from Amazon for $150.
Scopes and sights are a mix. I put old scopes on the Marauder and the Disco.
I ordered iron sights for about $10 each for the 2400KT and the 2540.
So, $215 up for the rifle, $60 up to charge it. PCP is definitely in the $500 range.
