do i need a larger tank or can i get away with the condor tank i want to get a maddog stock and build a 257

Im running mine with the stock tank and Mad Dog config. It has a 30.5″ barrel 1 in 14. Doug built the hammer, valve and “e tac” valve housing with quick fill and pressure gauge. I can even spin the tank off of the rifle because I notched out the stock to clear the fill nipple when spinning.

On a 3200 psi SP with 74 gr lymans I get around 8 to ten usable shots before a big drop off. Now if I am trying to shoot for groups I simply tether to my larger 4500 psi carbon fiber and run 3200 psi for each shot. But I have noticed when playing around that taking five shots not tethered does not change my POI.

Should be close to calling in some yotes. Waiting for the okay from a farmer here who has a bunch he wants gone. 🙂
