Been trying to fine tune my RAW HM1000x's for 1 MOA groupings at 50/100 yards and find the above two pellets less than optimal?

In .22 cal. have found the 18.13 grain pellets to be considerably more accurate from the Non-choked poly LW barrel. The only downside to the 18's is at 100 yards it doesn't take much wind to cause problems.

Also, in .25 cal. the 33.95 grain pellets are way better than their 25.39 counterparts?

I'm shooting everything at 905/915 fps, but have tried higher velocities to no avail.

Anybody have differing results?
If not, I'm perfectly fine sticking to what has worked for me(y).
If yes ... what have you done that works?

I’ve seen so many inconsistencies in those pellets that it’s difficult to get them accurate. I’ve seen some who have had good batches, but mine have always been crap. If you were to weigh and size them, I’m sure you’d have better luck, but probably only utilizing a third or less of every tin.

Personally I think the short Diablo pellets 18gr in .22 and 25gr in 25cal are more accurate than the longer counterparts.
Especially at short range. Inside 70-80y

The other thing I would mention, if u have a dedicated 18gr pellet shooter in the raw platform. If your good with machining, that platform has plenty power to launch that pellet with a 16” barrel, that’s roughly at long as the bottle.
Makes for a tight, light walking gun.

Well corny, for ME the 25.39 gr in .25 can't even shoot 1 MOA at 50 yards, let alone 100.
The 33.95's have been shooting sub MOA at 100 (low wind conditions). Everybody's gun is different.

How would the 16" barrel be an improvement over the OEM 24"? Just easier to handle/manage?
-> I plan to shoot slugs at some point and likely won't go to 16" anytime soon - but ya never know...

I hav a barrel in classifies that shoots the kings pretty awesome. Around 880fps
It’s the older barrel with centerized moderator.

That being said, I have a second raw with longer barrel setup for slugs. The shorter gun is just a great pellet shooter. Lighter, easier to manipulate

My BSA barrel supports .22 25 grain redesigned at 980fps for 100 yards in my RAW.

I have found the .22 cal Rangemaster 25.39gr pellets to shoot easily less than 1 MOA at 100yds with no wind. They are predictable in the wind. I use them in my RAW HMM1000X for Extreme FT with great results. I've tried all the other .22 cal 25.39gr pellets available right now with lackluster results.

I'll check into those pellets, but for now AoA is out of them:(

I've weighed mine, but not checked head size or skirts. None really seem damaged though....
I've got the sizing gauges, but didn't want to spend my life sorting pellets ......:p

I have done extensive testing with everything discussed. I find the AA series of 25.4 Gr pellets much more consistent in quality than I do the JSB - even though they are supposedly “the same.” I have a Wolverine Forester R HP, an FX Royale 500, and an FX Wildcat that all shoot the 25.4s lights out. All of my other .25 caliber rifkes prefer the 33.95 King Heavies.

I have tested tons of Brands in .22 hoping to project the subMOA for longer distances, but 70 M as far I could go with repeatability and consistency. I am talking of about 6-7K shots, or much more.
Beyond 70M to 100M I had to switch to .25 MK2, and undecided about latest batches of MK1s.
The 25gn MRDs I could have subMOA up to 50M even with Leshiy2 (which is really not a target shooting rig), but extending the distance to 70M or beyond the grouping started opening up. Lately I have dressed up that my L2 with .22x600 FX liners, still the MRDs cannot consistently deliver the subMOA @ 100. So no need for pushing that limit if doesn't work.
For 50M I really like the performances of 15gn AAE, 18gn Baracuda and 21gn Baracudas. I kinda feel the 18gn is for a hair better performer.

Can’t find the Daystate Rangemaster King .22 cal 25.39 pellets ‘in stock’ anywhere. AoA is out of stock until Christmas.

Was having some recent accuracy issues with a friend’s RAW HM1000x .22 cal with the JSB 25.39 RDs shooting at 50 yards at our outdoor range.

Spoke to Martin and he shared that he gets lots of calls/concerns from RAW .22 cal owners, who have the ‘JSB deep cavity’ 25.39 RDs relative to accuracy. JSB changed their dies about 2 years ago, and switched to making only the deep cavity skirts, which are not as accurate as the shallow cavity pellets. Supposedly, JSB is or will be switching back to making the shallow cavity because of all the QC complaints.

My own RAW HM1000x .22 HP does actually shoot MOA ( with the deep cavity MRDs) consistently at 50 yards, but rarely can shoot MOA at 100 yards with my JSB or branded .22 cal 25g RDs. Martin also indicated he is getting good feedback from users trying the Rangemaster Kings, but who has them in stock?

Until/ if I can find a new 25.39 RD solution from a pellet manufacturer, I can only reliably expect really good accuracy up to 50 yards with the current MRDs.

Kirk, I found like you, that the 18gr are the most flexible pellets at any speed and at most distances str8 out of the tin. The 25gr MRD are great if one puts the work in to sort, weigh and size then they shoot how they are supposed to. The original 25gr .22 JSB are much more forgiving as far as accuracy str8 out of the tin like said above....kinda shaped like H&n Sniper pellets. So, I shoot mainly the 18gr as I am too lazy and cheap (the MRD are pricey) and NSA slugs (lighter weight). Also, your barrel may need higher speeds or lower than ya think for MRD speeds for accuracy, lots of tuning involved with these.

Yeah Randy,
In the last couple of weeks, I decided to focus on doingall the little things right and recording my set-up. Just following that ... has shown ME that yes - for the first time I can shoot an 1 MOA at 100 yards. Matter of fact it happened ... multiple times immediately.

- Keeping my mind "out of the way" and practicing the same technique is next.

It also became apparent, my guns and certain pellets can shoot 1 MOA @ 50/100 yards, but .22 MRD's and .25 25.39 grain pellets cannot.

The problem is ... I spent 1 year amassing .22 MRD and .25 25.39 gr pellets when they were scarce - Now what do I do with 10 tins of plinking pellets?

Not going to shoot slugs this summer, reducing the number of variables confusing my shooting (which is likely very average:p).

Tom, all things you mentioned are true. The new JSB deep skirt 25.39 pellets just don't shoot well in anyone's guns, but the Rangemasters do. I have plenty of personal stock to hold me over until Christmas thankfully.

Kirk, I also purchased quite a few tins of MRD's like you. I sort and measure head sizes then size them for one tin, 250 for the JSB variants then 350 for the FX variants....but only shoot these occasionally so one tin lasts for at keast a year 😂, the 18gr are my go to pellet for sure. You could always sell them if need be.

Yeah, I've got 4000 crap MRDs. I was all set to buy a RAW but with the prospect of no good ammo being available I've held off.
