I have a benjamin marauder in .22 cal model number is BP2264S. Seeing as this isn't the field and target I don't think it is regulated although my shot count is pretty consistent. I could care less about shot count as I rarely go to range for extended periods of time and am fine with a little workout to pump it up again. My question is I'm doing small game hunting and pest control and want to get more power out of it. I'm currently shooting H&N Baracuda Hunter Extreme 18.52 gr zeroed at 30 yards. I am looking into the HUMA XXL regulator but the problem I see with that is I'm not sure what the shot count would be as well as I see no way to gauge the PSI on my fill with it. My other options are to mess with the tune of my unregulated marauder to try and get more power out of it but without a regulator, I'm worried it will be inconsistent. Either that or just use what I got and save up money to get an FX or something in a year or so.

Benjamin Marauder High Power XXL Tuning Regulator By Huma-Air

Huma-Air High Power Tuning Pressure Regulator for tuning your Benjamin Marauder rifle for maximum power.

Please any recommendations I'm trying to not dump money into a marauder I'd rather upgrade to something fancy later for slug shooting. Keeping it under 200$ what can I do to really improve this gun for my uses?
 
If you want maximum power, a regulator is going the wrong way. While the name of the regulator in question might lead you to believe it will gain you power overall, it will not. It is designed to allow maximum power under regulation.

Have you opened up or removed the transfer port screw? This is often overlooked by those who aren't familiar with everything on the gun. Lots of folks think the hammer spring adjustment is the only way to gain power. Since you mentioned that you aren't really sure whether it is regulated already ( it's not) that would lead me to believe that you are not familiar with everything on the gun.

What kind of power do you want? Are you sure you shouldn't be looking at a 22lr? Do you know what fps it is shooting at now? If not, your first purchase in the pursuit of power, should be a chronograph.

If you want max power for minimum $, do not regulate it.

My thought process was to regulate it so I can push the pressure up and get less shots at higher pressure = higher fps but regulated so there isn't a massive dropoff as I shoot. When you said "Have you opened up or removed the transfer port set screw?" Thats is what I meant by tune it. Should I just mess with those instead of getting a regulator?

Yes. You need to back the transfer port screw out for sure. It's usually set about halfway in from the factory which limits the power a lot. In order to do that without damaging the stock, you have to take the action out of the stock.

And you NEED a chronograph. Don't try to tune without one.

Thank you for the reply. Are the any good tutorials or tuning a marauder on here? This is my first PCP and I'm learning everything as I go.

There are but I'm not too hip on spending much time explaining more than I already have until you own a chronograph. Your manual tells you how to adjust the power levels. Do you have one? You can get one from Crosman. We can tell you how to do it (I kind of already did) but we can't know if you did it right unless you report the results. You need to buy a chronograph.

Have I mentioned that you need to buy a chronograph?

I just texted a friend of mine and he has a chronograph. Will try and get it to use sometime this week and reply here with results!

Excellent. Don't shoot your friends Chrono, lol.

I recommend not touching anything until you have it. Once you do, there are some very simple and cheap things you can do to increase the power from where it is. Marauders are quiet, they are usually hitting harder than you think they are.

I've shot plenty of squirrels and had them drop but for some reason lately these pigeons been eating pellets and flying away (I know they're dying cause I find them but they make it good 100 feet sometimes)

Take this into consideration, and don't take offense.

If you didn't know that you should start by adjusting the TP and hammer spring, or even how to do it, you certainly don't want to start your PCP experience by taking the gun apart to install a regulator.

You're going to be pleasantly surprised when you are able to adjust the gun. It will gain a lot of power. And you will be able to see it on the Chrono.

Still recommend just buying one. It is thee #1 tuning tool. You'll want to own one.

I fell into the rabbit hole of youtube and airgun forums looking into all the upgrades that I got focused on the wrong one. I had seen multiple places talk of adjusting the TP and hammer spring but I didn't want to do that without a chrono (lol) so I kept researching the regulators.

People LOVE to spend others money. Don't fall for it. Even after I've put the effort in here calming down your need for parts, someone will come along and tell you to throw money at it anyway. Don't do it yet.

Should I bite the bullet now and spend the 100$ on a chrono?One day shipping Amazon. Since you don’t want me to fall for it. This seems like the wisest use of money.

I can get him those results without having bought any parts.

See? I told you.

A $10 hammer spring will exceed those #s.

With a regulated Marauder the existing gauge will show plenum pressure, not reservoir pressure. You set the plenum pressure to some recommended value, usually between 1600 and 2000 psi. The Marauder reservoir max pressure is 3000 psi. You use your fill station gauge to fill the reservoir. As you shoot you will notice that the existing (now plenum) gauge will remain at plenum/regulator set pressure. Once the gauge needle begins to fall (from the set pressure) you know you are off the regulator meaning the reservoir pressure is now less than your set pressure. Time to gas up! You do not need a reservoir pressure gauge, only the plenum pressure gauge and of course a gauge on your fill station/whip/pump. A regulated Marauder can make big power and produce an absolutely flat shot string but it takes some mods beyond simply installing the regulator.

My Marauder is unregulated and it will shoot over 40 shots within a 15fps spread. Marauders do not need to be regulated. All it does is increase shot count. A better hammer spring will also do that. I know you know this... He wants POWER. Adding a reg will decrease the power potential no matter what. Saying otherwise is just plain wrong.

I’m more inclined to go this route. I’m going to buy a chrono which I would need anyway for a regulator and see what I can get out of my stock marauder.

A chrono is a wise investment for air rifles or PBs. There is no way to tune or adjust an air rifle without that is not mostly guess work.

That "tune kit" mentioned, well, long ago when I first got into PCPs I tried to purchase one. But, for some reason he will not allow purchases or shipping to the great state of Kansas. So, he saved me the money and I spent it elsewhere and I am now comfortable telling you, do not bother with that particular item even if he will ship to your state.
