RAW Rapid RAW HM1000X .25 or .30 cal

[glr59]

I've become a big fan of shooting a gun within the parameters of it's design. I've spent way too much over the yrs experimenting with "upgrades." Which leads me to a caliber question. I have a .22 cal HM1000X and would like to toy with a larger caliber. This is for punching paper and accuracy out to 100yards, no hunting. Within the design of a stock HM1000x is it pushing the gun too far with a .30cal? Is the gun going to be happier running with .25cal ammo?

Thanks for the info

I own a .25 and a .30 HM1000X. .30 caliber is a great choice for you since you already own the .22, and no, .30 cal is not pushing the gun too much!

My experience so far (.25) has been there is no wrong answer when it comes to HM1000x.

I once had an HM1000x, pre-Air Force, in .30 cal. It was very accurate at 100 yards. I recommend shooting AEA or JSB 45 gr pellets at between 860 and 890 fps. No exotic tuning necessary. I think either caliber would be good, but if you're using it primarily for 100 yard shooting, I lean toward the .30 cal. The .25 would probably work too and would be more versatile for other kinds of shooting due to lower ammo cost.

Go with a 30cal, 25 is very close to what you already have.

I have a .22 HMX and would opt for a .30 if mainly for 100yds and further like said above . You could also add an external plenum to your .22 and sling heavy slugs for 100yds....

I bought my RAW HM1000x .22 from SPAW in 2018/19 timeframe. I used it exclusively for 100Y BR Target shooting. Martin built it to spec with the Poly barrel to shoot the JSB 25.39g redesign pellets at 935 FPS.

In 2019-2021 time frame, GTA had a monthly 100y informal NUAH ( nothing under a hundred yards) target challenge, which I absolutely loved. I think I participated every month for about two years. The RAW shot consistently very well at my outdoor local range, and I had quite a few NUAH cards that were very solid. I had the random fliers and wind reading challenges, but I was interested in trying a .30 cal barrel to see if I could improve.

Sent it back to Martin and he put on a new .30 cal barrel and pellet probe. I shot the JSB 44.g and although it did well, I ultimately decided to go back to the .22 cal setup. I still have an almost new .30 cal barrel and probe keeping the gun safe warm.

If the AEA 51g and 45g were available at the time, I would have been more patient and practiced more with the .30 caliber. My sense is that you should try the barrel swap and give it a go with these two pellet choices. Quench your thirst.

Until I saw this post, I nearly forgot about having the .30 barrel in the safe. Was going to sell, but maybe I’ll hold off for a bit.

I've thought about the probe and barrel swap idea. Did internals have to be changed(springs) ? Did you have to increase reg pressure as well?
Funny thing about my .22. Martin sent it tuned to me for JSB 25.39 at 965fps. I've heard that is common. I've never been impressed, tried all the JSB 25.39 variants. Dropped the velocity still not impressed. Started reading about AEA and JTS pellets. After a few sessions I found the gun performs quite well at 100 yards with JTS 20.07gr pellets at about 980 fps. Go figure. I even tried the 25 gr JTS variant and it likes the 20 gr better. It likes the 18gr AEA pellets as well.
