Benji .25 Marauder what's a good tune?

[Willie14228]

As it stands right now I am shooting H&N 28.4 @ 800 fps with a stock spring.
I want a hard hitting with good accuracy and don't mind burning up air to get it 
Where does a stock Marauder top out at?

You can tune it up to around 880. You will get around 12-16 shots. Might want to look into the SSG from WAR. It was a great addition and I am averaging 844 with 28 shots. I believe Dairyboy and Addertooth are getting around 40 shots a 840. You may also have to enlarge the transfer port.

This is the spring ajshoots uses and what I had in my Marauder when you shot it a couple of weeks past. As soon as I find my extras I'll send you one.
Additionally the spring preload was turned in 1/2 turn (CW) from stock setting.

I have not gone further because I am pleased with current performance.

I have a bottled Marauder, regulated at 2,400 PSI. It has a .162 transfer port, and a TSS from WAR. Using the 25.4 grainers from AirArms, I'm getting 910 FPS with the TSS at its lowest setting. I get about 20 short per fill (3.2k down to 2.4k). It shoot 75 yard groups at less than 1 inch (inside range) if I do my part.

Thanks guys, I may install some mods, but right now I was looking for max stock tunes
I'm interested in seeing what a stock Marauder is capable of.

You should be able to get 24 shots in the 830-840 range with factory parts and wide open vms. That's what I got to with mine before FFH. Now I'm getting 32 shots in the 850-860 range. Good luck and keep us posted on what you achieve.
