I’m testing the chassis system HM 1000X.
This report covers:
- Reg adjustment
- JSB Exact Jumbo Heavy
- H&N Slug HP
- JSB Ultra Shock
- Norma Golden Trophy FT
- Shot count
Today we start looking at the velocity and power of the RAW HM 1000X PCP. This look will take more than one report because the power can be adjusted by the user. The adjustability is not major and it is for reasons other than changing the way your rifle performs. It’s more for tuning for a particular pellet and for increasing velocity after a long time when the hammer spring starts to take a small set.
The regulator, on the other hand, can be adjusted for larger velocity changes. Next time I will get into that.
I’ll start today’s report with the trigger. This one is set too light for my tastes. It’s two-stage and breaks as crisp as any 10-meter trigger. The problem is, it’s almost as light as a 10-meter trigger. Stage one is 7.8 ounces. Stage two is 9.2 ounces. I plan to adjust it next time and hopefully get stage two up to twice what it is now. And it can be adjusted for a single stage if you prefer.
The 12-shot magazine is a typical rotary mag, in that the first pellet is loaded after the clear window on top is rotated as far as it will go in the direction of the arrow. A pellet in that hole anchors the rotary part as the clear window is rotated and the rest of the pellets are loaded.
The magazine functioned flawlessly throughout the test. There are no instructions for how to load the magazine in the user’s manual, so you have to know how to load it going in. I guess when you pay two grand for an air rifle you either do know a lot up front or you have done a lot of research.
The rifle is filled to 230 bar through a conventional male Foster fitting. I know that’s a little higher than we usually go, but this is a regulated 50 foot-pound air rifle, so we should see a lot of shots from that much air.
Okay, let’s now look at some velocities.
JSB Exact Jumbo Heavy
First up were 10 JSB Exact Jumbo Heavy pellets. They averaged 1,039 f.p.s. for a muzzle energy of 43.47 foot-pounds. The low was 1035 and the high was 1043, so a difference of just 8 f.p.s. That’s what a regulator can do!
I said in Part One that I would be surprised if this HM 1000X was not at least 100 decibels. Well, it’s a good deal more than that. It registered 111.6 dB on my sound meter. I was shooting in the garage where sound is reflected by the concrete floor, but the RAW I’m testing is still as loud as a .22 long rifle.
At the end of the first string of 10 shots the onboard gauge registered 200 bar, so those 10 shots used 30 bar of air.
H&N Slug HP
Next to be tested were ten 0.218-inch 23-grain H&N hollowpoint slugs. I know some of you want me to test these in this HM 1000X and I plan to. They averaged 952 f.p.s., which generates 46.3 foot-pounds of energy. The low was 950 and the high was 954 f.p.s., so just 4 f.p.s. difference.
At the end of this string the rifle is at 180 bar.
JSB Ultra Shock
Next to be tested was the JSB Ultra Shock hollowpoint. Ten of them averaged 929 f.p.s. with a spread from 925 to 932 f.p.s. That’s a difference of 7 f.p.s. At the average velocity this 25.39-grain pellet generates 48.67 foot-pounds of energy.
At the end of this string the rifle is at 160 bar.
So far we have fired 30 powerful shots from this rifle and it’s still on the reg. I tell you that because of the next string, where I believe the rifle dropped off the reg.
Norma Golden Trophy FT
The Norma Golden Trophy FT is a new domed pellet I’m adding to the RAW’s test. It weighs 17.6 grains, so it should be the fastet of the four pellets we have tested so far. And the first shot was faster than anything yet recorded. This time I’ll show the string before discussing the particulars.
The average for this string was 1045 f.p.s. which generates 42.69 foot pounds of energy. But look at shots 6 through 10. I believe we are seeing the rifle fall off the regulator right there. If I am right, the spread of 12 f.p.s. isn’t correct. It’s probably more like 4-6 f.p.s.
There were 150 bar left in the rifle at the end of this string.
This is where a chronograph really earns its keep. The next string of the same Golden Trophy FT pellet will tell all.
Is there any doubt that the rifle is now off the reg? I won’t even bother giving an average for this string because it isn’t a string that should be used.
The previous string, however, can be used. Yes, the rifle comes off the reg at the end but the extreme spread is still very tight.
The onboard gauge is reading around 125-130 bar at this point.
What all of today’s testing means is that this HW 1000X gets 40 good shots at this power setting. As advertised and commented upon by owners, the RAW regulator does a fantastic job.
The RAW onboard gauge does not have a green zone, so it’s up to the owner to determine the pressure at which to stop. Given the level of investment required to own a rifle like this it’s a safe bet an owner will also have a chronograph.
Now we have a baseline on this RAW. Next time I will adjust the trigger and the power to see what that gives us. If there is enough of a change I may even do a third velocity test. This one will go long so stick around!
