I also fill my Gen I .177 Marauder exclusively with a Hill MK III hand pump. One of the things I discovered was that you can compensate for your fill method with some tuning of the gun. For instance, I fill to 2600PSI and shoot down to about 2000PSI and get 30 shots at a decent ES (right around 3% last time I checked). This keeps my pumping to about 60-70 strokes for that 2600PSI fill. Then I load the mags to give my heart a chance to slow down before the next shooting session. While I shoot my 30 shots, the pump cools down for the next pumping session. Of course, the Mrod does not have a 500cc bottle, so your mileage may vary.
