Has anyone tried the new 25 cal hades pellet in their 25 cal marauder? Would like to hear or see some results, cheers!

What is your guns favorite pellet(s)

Hey y’all just wondering what everyone’s 25 cal marauder prefers for ammo in terms of accuracy? FPS and shot count handy if you have the numbers, thanks!

My approach would be fitting a LIGHTER hammer and then destroke hammer travel until at power your after.
fitting a new REG will be whole lot more expensive with all the parts and pieces required doing so.

Should’ve stated 12ft lbs “at .177”

Has anyone tuned/taken their Custom Shop Regulated LW Barrel Marauder down to 12 ftlbs?

Just wanting to know if it is a regulator change only. (As far as any other new parts being added/required)

Looking to re-start with a regulator

According to the forum, my Last visit was: Wed May 18, 2016 10:38 pm, so I have obviously been away for awhile, and have probably only shot 100 pellets since then.
(I found a new hobby and have been busy with powered paragliding, its a blast and a cheap way to fly, and that has kept me away from my gun.)

According to my ancient notes in my gun case, I have a Gen 1 .25 cal Marauder tuned with a 3 O-ring bumper and I was getting 16 shots at 880fps with a 2900 psi fill.
There are a lot of other numbers, that all look like Greek to me now.
When I left the 3 Oring tune was all the talk and the original HDD was going out of style, and I think I still have 2 pieces of hose in my plenum as "de-pinger".

Now that I have returned, there are a bunch of letters that I am unfamiliar with, like TSS and others. And now as opposed to 3 years ago, regulators are working for .25 cals.

I would like to add a regulator to my gun and start shooting again. Any recommendations on where to start over, would be greatly appreciated. From what I have gathered over the past 4 hours of looking, its more than just adding a single item. If anyone has a list of recommended items, and their benefits, that would be great, and would give me an idea of where to start my research.

Also what happened to the Humor section of the forum? We used to laugh all the time, but I saw that a joke thread I started in 2013 is still on the first page. Has all of the humor/jokes died with the newest generation of shooters?

Re: What is needed after a huma regulator is installed

I am checking to see how your regulator install worked out. I have not been on this forum for about 3.5 years, and have not shot my gun much since that time. But I am looking to dust it off and start shooting, and I am thrilled that regulators are now being talked about. Last time I was here, the popular opinion was that .25 cal should not be regulated.

I am considering the Huma regulator, or maybe a kit that includes a new valve, spring and hammer. I am pretty lost with all of the info, and from the responses that you got, I am guessing that this has been discussed at length in my absence.

Good luck and I hope your mods turned out great.

Re: Transfer port size and second sources

If you don't have much success with the poly tube idea consider the possibility that the material expands and contracts quite a bit with temperature. Also there's a lot of heat generated in the transfer port area upon firing the gun. If you doubt that, just think about how dieseling can be done! The heat generated in the transfer port expands/contracts the poly tube material making it unacceptable and can cause a lot of variation in your extreme spread.

The only way I've found to increase the velocity is to increase the airflow through the entire gun. That may be a no-brainer but being somewhat new to airguns I probably have to learn all the things
old-timers already know. So I'll tell the story again:

I drilled the valve port out to .187 inches, made a copper transfer port (recently completed) similar in design to the original but massively larger with an inside diameter of approximately 0.2 inches
and about 5/16 inches outside. It required ordering some special square cut O-rings from The O-ring Store.com and tailoring them to 11/32 inches outside. I also had to mill both the valve and barrel
tops/bottoms to 11/32 inches with the end mill and drilled the barrel port to 0.187 inches as well. So basically the entire route from poppet to pellet is 3/16 inches in diameter. I tried to go to 1/4 inch
but that was too big and actually cut into the wrong area and ruined a perfectly good valve. Oops, but oh well, only one way to learn. So I learned a lesson. If I was a machinist and had the equipment
I'd invent a valve that could handle it but the best I can do right now is alter what Crosman Corp. sells. Saw one on JS Air rifles that had a 1/4 inch port but they evidently no longer sell it.
