RAW REPORT

So i got home early from work today and decided to take the .20 out and shoot it some more. Slightly breezy about 5-7mph wind,,,,this gun consistently shoots tiny tiny 5 shot groups,,,,impressing the hell out of me how consistent it is. My best 5 shot group measured 1/4" edge to edge outside diameter,,,50 yds. Ive had some shooters in my day but this rifle may take the cake. Officially naming her "The Blue Beast",,,,lol. I'm all smiles here with this bad mama jama. Pics or it didn't happen right?!?!?! 

These are just 2 of the groups i shot today but it will give you an idea of how it shoots at 50yds. The orange circle is 3/4" so you have a comparison.



















I flipped the one group over so i can measure it better and its just wider than a pellet that I'm shooting,,,,, The Blue Beast is a Lazer Beam!

Well I guess I’ll just leave mine in the safe now hahaha, that’s some wicked shooting Kdog, smaller then my 357 and 30 almost wow.

Well I’m humbled! I to have shot some pretty small 5&10 shot groups @ 50yds( w/ my .177 RAW’s), but not quite that small..., Do I see a run of .20cal’s coming back?

Yeah, that's insane: that's a 0.050" 5 shot group at 50 yards! Did I mention that I love 0.20 caliber? You're making me think long and hard about maybe going .20 cal for my BR setup when I get an action to go into my stock...

Sean what really gets me is when the pellet is .20 that's only 5/100th bigger than the pellet and that's the groups outside diameter....did I mention it was breezy . This is my first .20 but if there all like this that would be crazy. Regular LW barrel no fancy poly or anything. Speed is 800fps. 

Martins craftsmanship at its finest.

wow that is an awesome group from an awesome looking gun! (blue beast)

Don’t be fooled, the LW-12 groove barrels are fantastic w/ the lighter jsb pellets! My 12 groove regularly outshoots my poly’s... its the wind that kills you with that combo( lighter pellets/12 groove profile in skirt & head of pellet) honestly if I do my part reading the flags etc. 12 groove 10.5 vs. poly 13.4 the former is my choice for anything 30m or less! Maybe I got lucky with my barrel? If you go to my starting postal matches post in this section you can see some of those groups, Chas also shot some groups and posted 

 To Centercut and anyone else who is competing with a RAW @ EBR OR USARB NATIONALS GOOD LUCK & give em HELL! Show em what a RAW can do.. 

Those are some amazing groups! Good shooter behind it too.

Kdog,

The guy that sold you the gun has got to be missing that gun. Really nice shooting, and sharp looking unit.

I never considered the .20 but maybe I'm that crazy one. That thing is hammering the paper.

Threads gone a little stale so I decided to mix things up and investigate something that hasn’t been reported yet: power/velocity changes with hammer spring tension. I put my .30 cal barrel back on and shot JSB lites at the lowest setting, and then turn up the tension in 1/2 turn increments until I maxed out, shooting ~5 shot groups over the chrony to see changes in muzzle velocity. Will post the results once I have a chance to process them.

When done with that, I also remapped the BC of the 3 .30 cal pellets I have at the lowest and highest HS settings to see how the BC changes with velocity. Temp is about the same between tests, though humidity and pressure are pretty different. Will post those findings too. 

Lastly, I have data to show how muzzle velocity changes over a wide range of temps (~40F up to 97F) ao I should be able to box out the range of power adjustments in .30 cal setting and plot that too.



Oh, and I am starting to really like the JSB heavies in .30 caliber...

Stay tuned!

Here's the plot of Hammer Spring Tension vs. Velocity (muzzle and 1 yard) and Energy (@ 1 yard):





Shooting the JSB .30 cal heavies at 865 fps muzzle velocity yields 83 fpe. Man does it smack steel spinners hard! I get about 24 shots on this power setting. In contrast, when setup to ahoot the JSB Lites at 840 fps, I got about 40 shots per fill.

I’m now curious about ahooting the .25 cal JSB Heavies Mk I at 950-ish fps...

i love that stock SEAN is that a real ATLAS bipod,,i picked up a CALDWELL SHOOTING TABLE like JIMS and a ROCK shooting rest also a pair of HAWKE FFP 6 24 56 scopes ,last week i contacted DONNIE FLA and he let me know the RAW LDC adapters came in but were not the correct size so its gonna take about another 2 weeks to arrive ,HAS any one seen a RAW select black walnut stock thats the type of wood MARTIN uses,,

Pat,

RAW LDC ADAPTERS FROM DONNY !!!!!!!!!!!!!!

OK, I'm ready to purchase 2 as soon as I can. I'll have to figure out which cans I want to get for the .25 and .30 cal's.

Sean that is a beauty,,,,love a nice piece of walnut like that!

Thanks Pat! Yes, that is a 'real' Atlast bipod-I finally splurged and bought a PSR model after waiting for a CAL version and cancelling my order due to the wait on their redesign. Let me know how you like the Hawke FFP scopes-I still like mine a lot.

Yeah, the DonnyFL adapters should really help quiet down the bark on the RAWs-especially on the .30 cal now that I've got mine shooting at 83 ft-lbs of energy (it got a bit louder, LOL).

Thanks-yes, I take it for granted some times. The lighting was sufficiently diffuse this afternoon where you could see the grain nicely so I snapped a few photos of the gun outside to show the grain. It's a beauty for sure!
