RAW HM1000 / BM500 Tuning
- Thread starter Greisdor
- Start date
I have the 500bm with thimble.
I index my barrel in different ways for different things.
I can spin the barrel to get best groups. or I can spin it to be inline with the scope. parrell to it.
the thimble serves a few different applacations,.
u can spin your barrel 2 4 8 or 1o in increasements.
I like to rotate my barrel in the 8s or 10s.
gresdor.. did u ever use a raw with thimble?

Martin sends his rifles out already tuned to perfection. Other than indexing the barrel if you have a BM or TM, I wouldn't touch the thing.

i agree on not touching it ,,,but if its not living up to specs fps-es-sd= there are minor things u can do to the hammer spring ,,with a chrono you can tell if your #s are moving in the right direction ,,i would speak to MARTIN OR MARK ARIZONA office and have them walk u through it good luck PAT

It does not seem that they are working up to benchrest levels. So how to check reg pressure, how to adjust hammer, and anything else that may need tweaking. To send back to manufacture doesn’t teach u any thing. F x crown has info why not RAW.

FX Crown was designed up front as a gun that can be adjusted to users wants even if you wind up with something less accurate than the factory sent it out as.
The RAW's are as other have said are factory tuned each tested before they leave by One person, Martin.
I have shot a couple off the bench and they are fantastic shooters.
If yours are not do as Hynzie recommended and contact Marin or Mark.

There's normally no need to tune a RAW unless you want it to shoot a particular way for you personally. Most people send theirs to Allen Z for tunes. I think the RAW website list him as the person to contact for that.

Every gun will shoot different pellets differently. It has to be tuned if u want to win matches. Even the same kind of pellet has different lots / head sizes. It is unbelievable that there are only three people who can work on these simple machines.
I have already built a barrel tuner that has made a big difference in shot consistency. And I want to learn even more about adjustments to further make this gun shoot consistent shot to shot.

Call RAW. All there is is simply a hammer spring adjustment and you can adjust the reg somehow but not sure that's all you would need to know. Hammer spring adjustment is simple in the back there's a Allen hole CW increases tension CCW decreases. Reg pressure not sure and honestly wouldn't mess with it. Not sure you would need to do otherwise.
No one ever said only 3 people can work on them. Just nobody ever feels the need to as usually they shoot great and are tuned by RAW before they leave. There simple guns as you said it's not hard to figure it out.

Martin would never let a rifle leave his shop if it didn’t meet his high standards. Martin takes a lot of pride in his Air Rifles and as anything man made sometimes things can go wrong but are fixable and most of the time it only takes a phone call.

I asked the question "What do you mean by being tuned?" is I was wondering what you were after. Some may want a hunter some may want a gun to shoot competition.
Like others said above the hammer is as easy as tweaking it in and out. The regulator is almost identical as the FX regulator in the video above. RAW uses an o-ring under the brass knurled wheel that needs to be spaced as well. If you are switching weights of pellets and truly want it "tuned" Martin can swap barrels that shoot well with that specific pellet.
RAW is a simple gun. Sure everything can be polished, but the darn thing shoots good as is. Martin touches all of them. Not a lot of issues with the gun so they don't need to be sent to guys for repair. Most just call RAW to have it addressed. Try calling FX........ I can't even get an email returned.
I own both brands so I don't want you to think I'm a fan boy to either but here is how I equate them. RAW as a Porsche. Very reliable high performance gun. Just hop in it as a daily driver/shooter. FX is a Ferrari. They are high performance but need tuning more often. FX fully adjustable guns have more moving parts and o-rings. They are also the most innovative.
Everybody has an opinion on guns that is why we have so many different models. I see FX guns being sold to buy a RAW and vice versa.
