Hi guys. It has been a long time since I have asked a question on the forum, but I was wondering if anyone has tried these new pellets. These are the new design in a diablo shape. These are not the Strattons!
​I was planning on using them for the Extreme for the 100 yard shots, but my RAW HM1000X seems a little underpowered to handle these heavyweights.
​Has anyone modified their RAW to accommodate this new weight?
I have called Martin at RAW to see what his suggestions are....What are yours?
Thanks for your help

First off they are very long pellets and WILL NOT fit in the 12 shot magazines unless you mill out a good amount of their clear cover or single load them. Since you have the 1000"X" you have the power potential already as opposed to the weaker 1000 series. I have primarily shot them in my Huben K1 and with excellent results at 70fpe and tried them in other 22 guns as well including a hot rodded 50fpe MK2 Rapid and an AZ 22 TM1000 and had very good accuracy even shooting on the slow side. IMO its worth a try. They come in tins of 150.

If you are wanting to shoot at 100 yards in competition I would think the regulator would at least need to be upped with possibly a longer/bigger plenum fabricated and would recommend sending it to Allen Zasadny or Martin at RAW to tune it for the higher power unless you know how to adjust the regulator and have the equipment to test it.

If it were ME with the intention of winning 100 yard BR specifically using a RAW HM1000x platform, it would be in 25 or 30 caliber (I shot an unmolested 75fpe 30 caliber RAW HM1000x and a 50fpe 22 MK2 Rapid and shot a 60fpe AZ/Chip Smith 25 Custom MK2 Rapid).
If you are open to other brands, I have had exceptional results shooting at 100 yards and beyond using a Daystate Air Wolf MCT and a single shot Edgun Matador both in 25 caliber. and if I had to use a 22 caliber gun for 100 yard competition, it would probably be my 22 Edgun R3M or a vintage 22 FX Tarantula. All pellets weighed and sorted by head size of course.

Thank you for all your suggestions AJ...much appreciated. I have decided not to mess with an already proven rifle. I will wait for the 25 grain .22 to come out and do further testing with them. 

​And it seems that I misspoke about my HM1000X being underpowered. It is just underpowered in it's current configuration. The Rifle can be made to shoot the 34 grain, but when I have so much success shooting the 18,1 grains....WHY CHANGE!!

I do look forward to trying the 25grain pellets....If anyone knows where to get these, please let me know.
Thank

I've tested this 2,2 grams pellets in 5.5 caliber with different barrels: choked CZ with 450mm twist rate (1:17,7), LHB with 406mm twist rate (1:16) and LW with 500mm twist rate (1:20).

Here are the results with 1:16 twist rate on 50 meters distance


The other barrels showed quite the same result. Then I've tried shooting at 70 - 100 meters and was very disappointed... Grouping was just awful at 70 meters about 70-80mm with 10 shots (3").
