I had a Benjamin Akela in .22 (made by Kral).
Now I have a Kral NP03 in 22 and 177.

The Kral airguns have choked barrels.
They also hate harder pellets like the Crosman Premier.
No idea what is the point of the choked barrels.

At 60 yards my 2 Avengers and 2 Nova Liberty (non choked barrels) are more accurate with a variety of pellets including the cheap Crosman Premier.

See that's odd because my 22 mega will group cphp under a penny if I keep them going under 900 fps. 880 they stack at 30 yards, dimes at 40 and I don't use them past that. My 177 mega used to stack them out to 50, just rhe cheapy walmart packs too. Those were throttled back to 850 fps. Many a sparrow had their head removed by that gun with those pellets. It was so accurate in fact I got rid of my other 177s lol.

I just rearranged some gun parts again and came up with this mega np03 mix.

Had a 22 np03 barrel I knew liked the nsa 17.5 slugs so I tossed it on here and a dual hammer spring set up. 220 bar fill its getting 2 mags at 32 fpe with the NSA and gave me a damn decent 5 shot group at 40 yards. The patches on the target were from trying crosman hollows, they didn't fair so well lol.

Jsb 18s were doing okay but they're running a bit hot around 970 fps. Gave me a couple fliers.

The raccoon that crapped on top of my chicken coop better watch out, im planning on using this with the slug for him ASAP.

my refurb NP-03 really likes the .22 crosman premier domes at around 870fps,
a ragged hole at 30yrds

Premiers work quite well in my Krals although JSBs have been the best.

Kral Information Thread. “Contribute what you know “

Not sure if this is someone on here Dunno who that is and never seen that video before. I've modified a couple hammers, but the mega/np03 hammer comes with a pretty large diameter spring recess. I've had no trouble getting 32 fpe with stock ports, just higher pressure and large spring. I've...

the crosmans are for setting up and plinking.

After switching to a 12.5 lb/ft spring and polishing the bore, my Kral Puncher changed its ammo preference. It now likes JSB 18.13.

Hammer spring adjuster is set for a small amount of free flight. I have not yet chronied the 18.13s but it did 28-29 fpe with other pellets.

Kral Puncher .22 27 shots @ 25 meters. There are two 9s in there but the rest are Xs and 10s. The first 3 shots are with JSB Express.

update on the leaking NP03 refurb.....
i took it apart again and reinstalled the reg with more
silicone grease.
it seems to be holding after yesterday shooting over 7 mags thru it
with ES at only 11fps !!! the huma reg is working fine.
i get about 20 shots from 200bar to 160bar where the reg is set at.
its perfect for a truck/tractor gun for critters @ 30fpe with 18.1 jsb.
i hope it holds its balls now !! 👨‍🌾

These Krals are something. So many ways to tune them!

The Niksans look like updated Krals. It would be nice if they shared parts like the valve stem and o rings. I may be gravitating towards one of those as a future purchase.
