Picked up the .25 HW90 on the way to the camp.
Put about 30 pellets through it with the rifle, obviously, judging by the cocking effort required, at or over the max.  I can do 15 pull ups in the first set and 20 odd arm curls with 15kg so I'm no slouch strength wise, but that thing was a way bigger workout than the .22 was.   Took out the protector screw, gave the valve the gentlest nudge.... and the Schrader valve got stuck open and it emptied out and died in my hands.
Got back to base and re pressurised it with a BBB 400 PSI pump and a Rockshox Monarch Schrader valve purchased from Chain Reaction Bicycles here in Christchurch and just put 50 pellets through it at 19 Bar before the rugby started.
H & N Barracuda at 30 odd gn and Barracuda Hunter Extreme at 28 odd were a bit loose at that pressure but the JSB King Diabolo at 25gn produced 2 consecutive 1 hole groups at 20m so I'll work with them when the new scope arrives on Monday as the no AO 4 -12 X 44 is not all that suitable whereas the Diamond will be, I hope.
More to come, but the .25, as is the .22,  is sublime to shoot.  The Elite trigger, well, I'm no air expert, as you all know, but I've had some mighty fine centre fire and rim fire triggers, both worked and stock and that Elite unit is almost Rekord breaking.  Almost.
Thud, no twang, of course, and the recoil is straight back and at 19.5 bar, very manageable.
More to come once the scope arrives.
Anyone got any Sports Match Dampa 11mm dovetail 30mm dia rings for sale?

So put another 150 pellets through the lightly fettled HW90 and off front bag with crossover hold the groups tightened up a lot once I cracked a can of Kruzas H & N FTT's 14.66 that he sent with the 97.  350 mixed pellets in, including the 97's preferred Hades and JSB 15.89gn, and following the pellet testing protocol above, the last couple of groups were 1 holers at 20m of roughly 5mm.
Promising start.
It's coming with me tomorrow to my campsite at the Lake and between fishing and kayaking it'll test it out to 50m and see how that goes.
Another rifle that is pure bliss to shoot despite only about a pound of air let out and still fairly stout to cock at roughly 40lb.
I've just ordered a pump, gauge and Schrader valve connector so next step will be ladder pressure testing, whenever that kit arrives.
Quite noisy, as it has open sights, not moderator like my others and they'll be ripping at about 750-800fps at that grain weight.
Very distinctive operating sound.  No twang, obviously, and way less operating noise than the Magnum Gamos by far, plus the recoil is vastly different and far softer, plus linear without the flip and clank. Couldn't get the .25 tonight so picking it up in the morning on the way to Arthurs Pass.  I'll try a few rounds with that with the open sights once I've adjusted the barrel tensioner bolts and the stock screws are all tested.  Hopefully I'll get to see what it's like shooting rising troutTongue

I had a 6 -24 X 50 on a .204 for pest control and that, for the money, was good value and good enough glass.  Took a beating in the back of the ute too, which this one won't get, but .204 has about as much boot as a wet fart.]]> Tue, 09 Jun 2026 18:01:38 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=1375&PID=14643#14643 Tin Bum : kruzaroad wrote:Keep us updated... www.kiwiairgunners.co.nz/forum_posts.asp?TID=1375&PID=14642#14642 Author: Ashman

Just off the phone from Jacobs.  they're crediting me with the amount paid and I'm upgrading to a magnum/ gas ram rated NS Diamond long range 4-16 X 50.
Between the etched glass and air rated build, I think that'll do and only $240 for the upgrade,  Between that and the Sports Match Dampa's, I should get 50 shots off before sending it back for another upgrade.Tongue

Hey Ashman,

Not sure how much you know about air-gunning but here's a tip about re-leading your barrel in between trials of different pellet types, when trying to find your best pellet:

For example, if you’re trying three different pellets A, B and C then…

  • Clean your barrel first
  • Trial pellet A with 10-20 pellets and check group size
  • Shoot (waste) pellet B to re-lead the barrel.  Shoot about 10through the barrel - ignore group size.
  • Trial pellet B with 10-20 pellets and check group size
  • Shoot (waste) pellet C to re-lead the barrel.  Shoot about 10through the barrel - ignore group size.
  • Trial pellet C with 10-20 pellets and check group size

That wayyou’ll get true indicative groups of each type of pellet!  Many peopledon’t do this and they go around in circles trying to determine their bestpellets/slugs….

Enjoy!  Smile

PS:   Just tell me to shut-up if you know all this stuff!


Thanks and yes, I was made aware of that by Kruza.

I've got 5 different .25 pellets to try, mostly by H & N and JSB, so I'll be going through that exact process.  I have a scope I can use on that but I'm also waiting for the go ahead to be credited by the supplier for the NS that shat itself so I can put the initial cost of that in to something a whole lot better.

I've also got 9 different pellets from several makers for the .22 and I'll be testing them all tomorrow too, again following the same protocol.   In reality, it's the .22 I'm most excited about.

Yep, I saw your welcome in one of my earlier posts and thought "Slippery Slope"; what is this guy talking about?
And now I find myself rubbing lard all over, so I can slide more easily down that slope.Tongue
I think, with what I've got now, and the purpose for which they have been invested in, that SHOULD be all I need.
Besides, the guns are only part of it.
Hawke Airmax 3 - 9 X plus Dampa rings, there's another $750.  And then 12 tins of improper ammo to find what works, well, there's another $300 of which $50 will be actually useful.
I tell ya though, I think finding the right pellet is the funnest part of it.  That EUREKA!! moment where the clover leaf happens 3  or 4 times in a row and you go "Yep, sorted".  Then, the ranging and testing at different ranges for hold over, hold under etc.
It's a wickedly entertaining slope.  Lard and all.
