FX FX DRS Semi Pro

[Impact701]

I received my slug power kit from Europe Airguns today and got it installed.

I installed the slug probe 1st without installing the tungsten hammer weight.

I have my reg set at 170bar, the gun was shooting the 34gr H&N Heavy at 989 5 shot average.
The 38gr H&N Heavy at 946 5 shot average.

After the slug probe 34gr 1004 average and the 38gr 960 average.
The extreme spread went up from 5 to 9 fps on the 34gr and 5 to 7 fps with the 38gr.

Now for the tungsten hammer weight.
I measured my hammer spring adjustment at 9mm from the back of the receiver. I made a guess to turn it in to 6mm since the head of the tungsten hammer weight is 2mm taller and definitely heavier.

I actually didn't gain any velocity after the installation of the hammer weight my average 1001 fps and extreme spread was 10 fps. So I tried adjusting more tension but speeds got slower so I did ⅛ turn out until I got this 12 shot string

I was running low on air in my SCBA tank so I didn't get to shoot the 38gr again.

It's close to a DRS Pro with the addition of the slug power kit, carbon fiber sleeve and the picatinny scope rail.
Of course no match grade trigger or the MDT Elite Chassis.

Is this with the 700mm version or the 600mm?

22 700

22 700

The 22 700 came from FX with the SHP plenum, heavy slug liner and the heavy impulse valve. Like the Pro.

Gotcha, do you find it to be relatively quiet given the power it puts out? And do you know how long it is with the moderator you have on? You're putting some really good numbers on paper

It is 52 inches long with the STO Falx that is 6 ½ inches long, plus I have a 1 inch 3-D printed buttpad spacer.
The Falx does a great job quieting it down. Otherwise it is quite loud.

I don't usually like to post groups, but this group goes wth the crony results.
This is shot off of a sandbag no stock at 90 yards.

Is that a 10 shot group? Looks to be about an inch? That's pretty good!

Yeaah at 52in that's about as long as my at 44 long woth a donny fl Fx mod. But I take it the DRS is super light.

I have a Ninja air tank and a
re- purposed Camelback back pack that I carry out to the pdog town. That will provide a day full of shooting.

You don't always need 500 shots from a single fill. I would be much happier with 20 extremely consistent shots over a bunch of various shots.

That's awesome!

I understand not everyone needs a ton of shots, everyone has different needs and wants. For my type of pest control, I prefer a larger shot count as I shoot a lot and don't want to be refilling my gun everytime I go through a mag or half a mag depending on what gun I have. For me that would spell having to refill my tank at the end of the day and not just the guns.

I have the same set up. Paintball bottles and backpacks are a perfect set up for a day of hunting.

ou don't always need 500 shots from a single fill

Indeed. Though i must also admit that is is a thing i look very much at when looking at a new rifle, which are really stupid CUZ i always shoot connected to a 9 / 12 L bottle and so shot count are no issue.
