The first rifle I bought was a HW 90 .25, under my buddies suggestion. I had no clue. Well, I could hardly Jack it. Monster. Hated it. It’s a wonder I bought another Weihrauch.
Last January I bought another 90 .20 cal. and pump and gauge, after reading Jayjay”s post on the 90. I had lots to keep me occupied so the 90’s were on the back burner. Then a member Froggy kept posting and raving of his HW90 .22 on my post What Springer did you shoot? I got the itch to try the pump and gauge on both my 90’s. I could take back things I didn’t even steal. Both guns are now in my rotation. These guns are diamonds. Amazing when you can change the power of the gun with ease. The pump and gauge simply make the rifle a dream to use. Crow

Even the hatsan ram that takes a probe can get tuned nicer/ find a sweet spot..

Virtually all Theoben piston guns and as mentioned some Hatsans. Remember there are factory limits that should be adhered to prevent damage to the user or gun.

Seems they all say the theobin rams got that limit stamped on them but can't remember if the hatsan ones do or not.

Theres printing ( painted) on the hatsan rams but mine was pretty much scraped off to read it.lol. the hatsan 25sc now shoots a cphp 7.9 at 485+/-

Seemed new factory filled like 600+ ?

Anyone opened up a Norica gas ram rifle?
Are the gas ram adjustable?

Just wondering if the Norica Omnia can be easily de-tuned to 12 FPE

Email Norica and just ask if they are or not. I have a spare Norica gas ram for my Deadeye GRS but it's a sealed unit. Not betting they've changed, but it's been a few years since I bought the one I have. If memory serves from the thread the Omnia designer posted, the action being used is the Norica Hawk, so you might want to look into where to find spare parts should you need them.

Hatsan rams, at least the ones I've played with, all say 150 Bar Max on them but are usually right around 125 from the factory. Some have a bleed valve to tinker with the pressure, some don't.

Can't honestly remember where I read it, but someone said they bought a bicycle shock pump and the fittings to charge a Theoben ram and paid way less than what the pump kits cost.

Just emailed Norica. Will see what they say.

Just did a chat with Pyramydair asking if they have a 12 FPE version or can special order one...OMG. Talk about a waste of time.

Does anyone own a Norica Hawk? ...Would hate to impose...but if you could tear it down to see if the gas ram is adjustable (or if you tore it down before, do you remember if the gas ram was adjustable?).
or
Anyone who just recently bought a Norica Omnia...LOL...hate to impose but if you could tear it down to see if the gas ram is adjustable.

for either gun...how was the accuracy? 1/2" at 20 yards? :) or better?

Thanks.

Edit
No reply from Norica. as of today 4/4/23

For the Pyramydair team. I don't know if they got knowledgeable staff manning the Chat. I understand it's a new product. I specifically typed gas ram and asked if they have a lower power replacement gas ram for the Norica Omnia. The guy responded with we don't carry that spring. At that point I reminded him that it was a gas ram not a spring and do they do special order? He got huffy and typed we don't carry that either and we don't do special order.

The Omnia is a brand new to market rifle, especially because of that recoilless housing the action is parked in and why people are talking about it and while I've seen a couple shooters say they wanted one, they probably don't have them yet.
Also probably why PA has no idea what to tell you since it's that new. Been awhile since there were any US retailers selling Norica, so PA now importing/selling them is a pretty big thing in itself.
