Sunday will be my 1st time out trying the 800cc tank and .25
Well looks like I am going to do a early look over of my favorite gopher fields Sunday and have my .25 package tested over a chrony and ready to go. Turned down my valves on both the new 800cc main tank (thanks Walter) and as well matched my backup 430cc tank to just shoot JSB .25s at 970 fps with a 2500 psi fill to conserve my scuba tank volume. This velocity pellet conbination will only drop 7 inches and still deliver 30 ft lbs at 100 yards with a 25 yard zero. Also have my regulated 2000 psi HPA tank setup to try out but it only shoots the .25 at around 790 fps a little slow for longrange work.
Main tank is doing over 50 shots and the backup around 30. Also rigged up my laser rangefinder to just screw onto the 20mm scope rings as I found I mostly use my rangefinder for when I am shooting at one vantage point out to 120 yards and not while walking.
Oh well the trigger finger is itching to send some .25s downrange.

Well today was not the best. 🙁
Overcast until noon, windy as hell, and the road into the property had what was left over of a big snowdrift and lots of mud. The farmer said to be careful not getting stuck guess I was the 1st one in this year, thankfully the Jeeps quadra trac and tires didn’tet let me down.
Due to the wind I did not do much pesting I was using 4 Mildots just to get on target for the wind, but the .25 JSBs worked quite well in the wind.
After about 400 shots of .25 I definately can say the advantages of increased airtank volume (800cc) are worth it. This setup worked so well I never once used my backup tank, it just shot and shot.
(Thanks again Walter).
Here is where I shot from and whacked a few gophers on this dirt mound:

Here is one that got a .25 JSB in the gut:

Still snow up there:


My Jeep, the way out really made a mess result was 10 bucks at carwash:

And a pan view with the lovely wind:

I was hoping that by lowering the .25 JSBs to 970 fps the overpenatration problem would be addressed but the .25 still passed thru on body hits even at 100 yards so I think I am going to try the 2000 pis regulated system at around 750 fps.
