RAW REPORT

[nomojo65]

Yes, every barrel does have it’s unique characteristics, you do basically what I do now,but at first with the LW poly’s I was deep cleaning basically every card because I thought it was more accurate this way?, but learned that I was basically going through a accuracy curve each card or session!? (I have to learn the hard way the only way I know I guess!) and have been doing a little experimenting as of late because of some inconsistent performance (poly barrels only) I was using same process as my 12 groove and my Steyr barrels, but have changed things up on the poly’s? So far it’s encouraging? Have the whole winter to sort it out! 

 

[nomojo65]

Well because I was up! And curious about a couple things?,thought I would do a 50 shot chrono. String: BM-500 w/poly barrel all stock from Martin, Indoors 70deg.,13.4gr jsb 4.52 head dia. Not weighed straight from tin! 1st shot clean barrel = 802fps, 2nd=809, 3rd 814, next 47 shots were from low of 811fps to high of 822fps! For an E.S. of 11fps I’m not counting first 2 shots as I normally fire @ least 3- pellets to season barrel after cleaning before shooting my first card! As a side note I fired two cleaning pellets (together) after the 50 original chrono shots, then fired a 10 shot group @ 16.5yds, Thought this curious also first 25 group on (right) some vertical! Next 25 (left) more Horizontal!, last 10 a hint of vertical? Now will say first 50 not to concerned about group size!

Seems like you were finding the same thing I was in my thread on the effects of barrel cleaning and how the effective BC 'recovers' after cleaning the barrel. I noted that it took about 50 shots to 'season' again before the BC stabilized after cleaning. Here's the link to the thread. Good stuff-thanks for sharing!

Yes Sean, I’m probably a little late to the party... but am finding that the poly’s seem to shoot more consistent- fps anyway “seasoned” not sure I want to say dirty @ this point? Now something else I am seeing or think I am? Is consistent fps not always translating into same accuracy on paper? Lots if variables here I know!, still gathering DATA & trying to interprete this information to the best of my ability? Lots for me to learn and I know many others, Martin, Mike, owner of Thomas airguns have been all through this way before my feeble attempt!,but I’m learning... slowly! Also want to make this clear, many, many other competitors much more knowledgeable than I (ken Hicks for one) and about 30 others... ( Not the Utube wunna-be’s either!) I could name but never actually met, these shooters we could all learn much from, if I could know 50% of what they’ve learned competing I’d be a Rich man indeed...

my raw is a 500bm 177. my findings are this.

gun as sent to me from martin the es was very low for a 120 shot string. less than 30 fps.. for first 100 shots it was under 10 fps. gun was doing 915fps with jsb 10.3s

then year later I loverd the hs tension to 890 and both my es and sd got really bad. and accuracy seemed all over the place. but I haven't had a chance to check for accuracy or

es and sd now that I have the hammer spring turned up to where martin had set it . I will let you guys know when I get a chance and post my findings here. hopeing it goes back to normal? I should have left the hs tension where is was!! but we all know us raw guys love to tinker

 

[Hotbrass]

Salt? What the hell? Do you dive with the same tank? I've been using a Carette to fill my 45min tanks for about a year now. Faster than some, slower than others but a reliable source of clean dry air for my RAWs. Uj

Thanks Uj. I am looking at a few units. Carette, Air Venturi, Omega SC and Daystate.

 

[nomojo65]

The BM-500’s I believe, Martin sent them out to shoot 810-815 w/ 13.4’s to make USARB-HV requirements of 20ftlbs or under! Both of mine are anyway, but he also knew what class I would be shooting in, still I believe all BM’s were set up this way unless they were for a different class? etc. now I’ve never adjusted Regs on any of these guns or TM for that matter, the HMx I backed off H.S. Tension a little that’s all and everything settled in very quickly and consistently.

 

[SMH77]

Speaking of BM500, I think I've located the missing piece to this picture. Now I just have to pay for it...

 

[nomojo65]

Barreled action? Or just the barrel? Is that inletted for X- action?

 

[SMH77]

Barreled action (.177 cal, Polygon with a thimble). BM500 (non-X) for HV class. Silver action...

 

[nomojo65]

Nice!, you will love it!

 

[Crusher]

Just because I couldn't find one online anywhere, here is a PDF of the RAW manual. Yes it is sideways because it is a small book. But you can print it out and read it if you don't have one handy.

Also, switching from my blue laminate LRT stock to this beautiful BR stock. The LRT doesn't work well with my rest. So I may have it up for sale shortly if anyone is interested.



Here is the sweetness that is on its way to me now:

And here is the pretty girl in her current LRT blue shoes.

 

[SMH77]

Nice stock Crusher-both of them! Is your action an ‘X’ action, or just a normal HM action?



Sean

 

[jps2486]

Sometimes the hammer and the bore that it rides in, gets greasy and will affect the SD and ES. Carefully remove it and clean both. Lubricate with a very light coat of a very light lubricant. Note how all the parts come out so you can re-assemble correctly. You will have to take the trigger out first.

 

[Crusher]

Any good videos anywhere on doing this procedure? I'm wondering if the cold has just made whatever grease is in there, thicker and causing the problem.?



Yes my gun is a TM1000 so that blue stock would fit your TM or BM.

 

[crgabel]

I received my DonnyFL Emperor from SPAW tonight.

Right out of the box no mods it shot great. It ends up 8" longer but i can deal with that.

Db before (stock from RAW was at 97 Db

With the Emperor installed it came in at 59 Db. that's a 38 Db reduction.

[Imold]

Nice, I might need to get a adapter for my HMx .30 and try my Emperor on it now.

 

[mubhaur]

In order to handle the noise, I disassembled the original moderator, got made holes from where the sound could exit and wrapped a felt on the area where these holes were made.

Now my RAW HM1000X .25 60 ftlb is reasonably quiet.

Mine is now doing 75 db indoor without pellet after this mod.

Accuracy is spot on.

Regards,

Umair Bhaur 

 

[SMH77]

Good info Umair, thanks for sharing. I wonder is adding additional (small holes) to the outside of the shroud (like on the DonnyFL version) in addition to the fet you installed would further help quiet down the sound? Just a random thought...
