I've got both the 500mm and 600mm barrels for it. I can get those speeds with both, however with the 600mm I can fit on a 580cc bottle and relax the regulator. My setup for 23 grain NSA and Javelins is first reg at 170, second reg at 140. Power wheel on 7. I've got the hammer adjustment screw out .124" I'm using the slug power kit (probe and heavier hammer weight). With this, I'm getting 5 mags of shots.
Currently, with the reg set to 130 bar or so and a 700mm barrel....around 1075 fps. Maybe not quite that...
That's plenty fast, but if you need an excuse to buy a new gun, you have my permission!
Excellent point. I too prefer going lighter for slugs. Less wear and tear on your rifle as well. I shoot the 23's in my wildcat and I have the the 800mm tensioned barrel on my .22 M3 Impact. I shoot 31.2 grain out of that one. Way more than enough power, shoots flat and accurate. And as you said pellet-like shot count. A smoking fast, light slug is devastating. I've noticed that Roelf Vorster on his YouTube channel "AirTac Hunting" seems to prefer the 21 - 26 grain slugs over the heavies. My personal opinion is if you feel the need to sling 40 grain or higher slugs, it's time to move up from .22 to a larger caliber unless you enjoy replacing parts on your $2k+ air rifle a lot.
