New RAW chassis - disappointing 1st day

[Heavyopp]

Shooting them a tad to fast will cause a corkscrew too 945 is pretty hot for pellets

Actually Ton at airforce/raw had suggested turning the gun down a tad — something about me being at sea level.

recommended running between 920-930

This is all coming from my dealer, Bin at the pellet shop. Reached out to him from the range yesterday and he reached out to Ton.

Just to jump in here again, I doubt there is anything going on with the barrel. I wouldn't go scrubbing the barrel if it were mine. I have proven to myself that the RAW needs a moderator if for no other reason than to strip the turbulent air off the pellet as it leaves barrel. That's what the original giant muffler on the older RAWs did. Having said all this, there may be another factor to consider — 22 cal is not at it's best at 100 yards. Start at 25-30 and see what it does with weight sorted and head sorted pellets. Then move to 50 and see what it does. Here are a couple targets to illustrate. First 25 yard with teeny groups then 50 with larger, but still sub moa groups. Lastly 100 yards. These were shot on different days, but all under ideal wind and weather conditions.

It’s not that I was expecting to shoot quarter sized groups at 100 with pellets, but I kinda was expecting to hit the paper.

Again, I appreciate all the comments and suggestions, keep them coming. we’ll get this worked out.

Did you start out shooting 100yds, before shooting at 30-50yds? If so reel it in and get a feel for the gun and try to take out as many environmental conditions as possible.

RAW’s are usually pretty consistent and accurate, mine have always been pretty pellet fussy. I blame that on the Poly barrels. (Another topic for another time)

Another thing, I’m shooting the FX version of the MRD being JSB MRD is hard to find. Supposedly there is no difference between the 2. JSB makes the FX version and its just relabeled.

Is there a difference? Anyone have both versions In hand? Pictures?

 

[SAZ]

Not great pictures, but hope it helps somehow.
No. 1 is the Jumbo Monster Diabolo (NOT Redesigned) 25.39
No. 2 is the Jumbo Monster Redesigned 25.39
No. 3 is the FX 25.4 pellet

thanks for those pics although hard to tell — between 2 and 3 can you tell any difference having them in hand?
how about the skirts?

The original Jumbo Monsters won’t shoot worth a plug nickel so don’t waste your time and money.

If you talk with Martin he WILL tell you to shoot that barrel with a moderator so I’d start there.

 

[SAZ]

Sorry, pics are not great but it's as much of a closeup as I can do with the phone camera.
JSB-MRD is on the left in both pictures, FX is on the right in both pictures.
I can't tell a lot of difference between the two. Skirt on the FX appears to be slightly deeper & wider?

 

[joelayfield]

maybe a silencer , then grab a chronograph and start dialing the hammer back a little

 

[Heavyopp]

Turned it down to 926 or so just a little while ago. Can run a chrony at home. I’m hoping tomorrow I’ll get to the range in the morning. I’ll be better prepared.

Any muzzle brakes or even those Rowan engineering air strippers worth anything?

 

[corny]

Also…try hand loading.

Never used a brake. When mine wore the huge diesel muffler on the end of the barrel there was an air stripper inside it just beyond the not so effective moderator. The gun shot great but was a tad on the not so neighbor friendly report. I couldn't stand the sight of that huge thang so I sent it back and Martin removed it and installed the 1/2-20 adapters which are now a standard item. The last thing he told me is that "you will want to run some sort of moderator as it does help increase the accuracy of the rifle". I had a Ronin, Trident, Tatsu and FX/Donny on hand and tried them all with similar sound damping effectiveness. Ended up using the FX/Donny as it had the most notable accuracy benefit over the others.

Been hand loading due to the ARC rings I had are a little too low for the magazine. Can still get behind the scope but its not ideal. Will order new rings on Friday.

My problem is my location. New Jersey.

That is an interesting comment from Martin. Maybe it's just coincidence, but that has not been my experience. I don't think I have seen any consistent relationship between accuracy and the use of a moderator. But I trust his experience, and I'm sure he's correct.

You’re from Jersey? What exit? Hahahahaha….I grew up in Summit NJ

 

[Heavyopp]

Had a better day today. At least I can keep them on the paper. Mild winds, pellets plucked from the tin. No sorting.

 

[Ranchibi]

Seems like your groups are shrinking. Still, try adding a moderator and see and make sure to size the Redesigns as they are known for fliers....have you tried a different tin? Also try some 18gr.

 

[joelayfield]

you need to talk to motorhead "scott" and there is a few other guys that maybe can help . i would back that hammer down some
