I'm an admitted Impact fan boy. This is number 5. I just picked it up today. So I haven't been able to field test it. The things I noticed and liked is the shorter throw cocking. Very smooth and easy to switch sides of the cocking arm. I forgot to weigh it but it feels lighter. I went for the Sniper model that has the 700mm barrel and 580cc bottle. The included moderator does a great job so I didn't opt to put a Donny FL on it. This one is a.25 set up to shoot JSB MKII 34 gr pellets.
The M3's are a dual regulated gun. The shop set the first reg off the bottle at 150 bar. The rear reg is at just under 100 bar. So many subtle changes over the MKII. Hammer spring can be adjusted without a allen wrench. Power wheel is much more incremental in adjustment. Plenum has 25% more volume.
I had not cleaned the barrel or anything. Just sighted it in at 28 yards and wanted to see what it would do. Was not disappointed.
28 yards.
Took it out to 50 yards. The wind had come up some. Not terrible.
I also tried some FX Hybrid slug/pellets and they shot well too.
Here is the chrony reading.
I think the shot count will be really impressive. I started at 230 bar and after two 28 shot magazines it was here.
Great airgun! Mine is also the sniper model but in .30 caliber. I have set it up for shooting from the bench @ 100 yards and it accomplish the task beatifully, grouping in 1-1/2".
I've set the first regulator at 155 Bar, the second regulator at 105 Bar, Power Wheel at 8, fine tuning wheel at 3.5 and valve opening knob at 4. With this combination it is yielding with the FX 44.8gr pellets, 931 fps avg. for 40 rounds, 7 fps xtreme spread, 86.3 fpe and can give 80 good shots from a 250 Bar air charge.
I've since changed the FPS to 920 with JSB 33 gr MK2's. Here is a five shot group at 100 yards.
We're close to the sweet spot, I guess?

Hey Guys,
I have just started tuning my Mk3 Sniper Bronze .25 cal, I have only had it for a few weeks as we are way behind you guys back in Australia with supply etc. I am currently using the JSB 26 gn Hades and the 34 gn King Heavy Mk2 on the same settings . Accuracy is ok at 50m but not quite what is posted by pluric. Getting flyers occasionally.
My Settings are -
Valve 4.5
First Reg 140
Second Reg 100
Getting 930 fps with the Hades and 870 fps with the 34’s.
What settings are you guys using for the last pics posted getting 920 fps with the Heavy’s. I realise every gun is a bit different but would appreciate some starting points to go with.
