PCP Woes - Too much pressure, too much power

[datilD]

Without doing any serious mods like drilling out the transfer port or installing a reg I could easily adjust my Marauder down to the high 600fps with just a WAR TSS and a MDS hammer.... I only put two magazines through at that setpoint just to see how many shots I would get, but it wasn't want I needed for my uses so I tuned it back up to 875fps at 2800psi.  All I'm saying is that it can be done without a regulator, you just won't have the super consistent shot string as the reservoir pressure goes down.

I beg to differ.  Just look at my unregulated .22 Synrod signature with TSS and MDS.  31 shots @ 1.6% ES at ~30 FPE.  Much flatter (so far) than my regulated .25 Synrod.

But you don't want to only fill to 2000psi... I doubt it would work so well at those lower pressures.

  That fact keeps getting overlooked in this thread.  I want to keep the fill to 2000psi, so I don't break too much of a sweat.  I am 50 and in good shape, but the fill from 2000 to 2900 is much harder than from 1000 to 2000.  The 2000psi fill also gives me the option of using a standard 3000psi SCBA tank for fills.

buy a scuba tank for $200 bucks and get it filled at you local scuba store for $5 or check you local scuba store and see if you can get a used one at a good price

  I talked with the local dive shop, and they will sell me a used tank with hydro test for $125.  Fills are $7.  I'll continue to use my pump for a while and see how that goes.  A tank is in my future, though.

Well you said you sold the Marauder and ordered the Maximus so no point in going further.  I believe you will be happier with the switch and hand pumping.  I pumped up my two Marauders yesterday to 3000 and 3100psi from around 2300psi on each (tank running low) and it took a little effort but was not too bad for the rare occasion that I would do this.  I do like my tank much better and do shoot more with it.
