Airgun Technologies .25 Uragán 2 - 700

Short and sweet. This gun is pretty dang awesome. The Altaros slugs are pretty dang impressive. 175 yards and does it over and again:

what the heck. I have currently .25 cal tuned for AVG 78-79 joules for Jsb exact king 33.95, and i got told that i need to choose Lower weight slug, if im gonna shoot slugs, and that 40 and over would be too heavy ? im confused now. I am beginner with these.
I’m not a beginner and know these platforms well. I’ve upped reg to 170 bar and tuned/adjusted hammer spring to match. Is yours a 600 or 700mm barrel?

So the weapon is this - >https://aselkonarms.com/urun/pcp-mx5/ pipe lenght is 550, with my silencer probably 700. Rifled barrer, twist rate 1:15. Stock shoots 840/890 fps / 61-62 joule AND assuming they have used 24 grain or something i think ?. Now it shoots those Jsb 33.95's @ 271 m/s average, so like 900 fps with those. So i think i definately buy some slugs now, but can i realy go as heavy as 49.5 altaros ? It was a Big 1x1m rifle target, and i had to sigh

You’re shooting a completely different boom stick. So yours might only be good for pellets

Totally different gun so can't be compared. I'm not sure we have those in the US? Haven't heard of them. But yeah Uragans are way different.

You may have luck with a 30 to 36gr slug. As has been said, your rig and the Uragán 2 aren’t anything alike. Your barrel does have a favorable twist rate for slugs. Try some H&Ns, they are great.
