  • Question
Hatsan Barrage psi ?

Is there a way it increase the pis so the the pellet has more knock down power? I tried squirrel hunting but after 20 or so yards the pellet seems to not penetrate the squirrels, I have the 25 cal also I’m looking for a more powerful 25 cal bolt action that is left handed if any of you have suggestions, thanks in advance

Benjamin  2015 Marauder 25 cal low velocity

My 2015 25 cal Marauder is stock and I assume is a Gen 1. When I first bought it I recall it shooting in the low 800's using JSB's 25.39's. The last couple years it's shooting in the upper 600's and is accurate. My preference is to get the velocity back up in the low 800's. I've search youtube and forums trying to find a solution for increasing the velocity. I've opened up the valve metering 4 CC turns and have backed the spring off and turned it CW one turn at a time but the velocity seems to stall in the 680's. It appears not to leak off pressure while stored.

Are there parts I need to replace to regain velocity?

I've followed the information in this link down through where it mentions increasing hammer tension 1 turn at a time.

Dragon claw II

I am having trouble with my Dragonclaw II. I cannot seem to get it to shoot straight. I can always hit the target but never get it zeroed in. I have tried with Seneca round balls, hollow point, flat nose, and even the 330 grain flat nose slug! I have shot boxes of ammo trying my best. I always shoot my shot with the pressure the same for 4 shot groups. I'm just not having any luck. Any advice would be greatly appreciated!

Diana  To tune or just respring?

I have a Diana 48 .177 which I purchased used around 1990. Though I have not shot it much the past few decades, I ran it across the chronograph last night with some 30+ year old Crossman premier 7.4gn wadcutters, and some H&N Barracuda Hunter Extreme 9.52gn pellets that I was able to acquire locally. A tissue over the breach does not move when fired, so I suspect my underwhelming energy at just under 12 ft-lbs is likely just a tired old spring. This is a US market gun, so I would not think it to have been a restricted version. What might I expect out of a tuning kit vs just a new spring? I would like a bit more power for small game hunting, maybe somewhere closer to 18 ft-lbs would be nice. The gun seems smooth enough, but I don't really have anything to compare it to. I was looking at the Air Riffle Headquarters VRT kit or GRT spring, either of which seem to be drop in compatible to an untuned Diana 48. I don't understand what the VRT or GRT mean. There also seem to be several different piston seals available, I am not sure what the differences between them are. Thanks in advance for any guidance or options.

Hi...
Need help from everyone... I have problems with my angled manometer, it started to leaks, and after a careful observation it is the x ring that had been broken... Anyone knows the size of xring? Or any solution without the x ring? Because in my country i can't find any store selling x ring...

Thanks

Other  alternative ways to achieve spin stabilization

Hi peeps,

A newbie here. Over the past few months I've been researching pcp air rifles with the goal to design and make 1 (for) myself. During this process, it got me thinking of alternative methods to achieve spin stabilization of the pellet/slug other then rifling the barrel or making a polygonal barrel with a twist.

I've been wondering, is it possible to spin the pellet through airflow alone? By "rifling" the airflow behind the pellet, which in turn would spin the pellet as it is propelled forward by the air. The reduce friction and increase the effect of the "rifled airflow", maybe a very small gap between the barrel and pellet is needed.

Any insight and/or related comments are greatly appreciated.
Also happy holidays everyone, hope you have a good one.

FX  Fx impact M3 sounding louder?

Hi all.

I own a Fx impact M3 in .25cal, i have it tuned to shoot 39g slugs at 960fps, i have used the same tune since june 2021, everything internally is stock, Airmarksman backbone rail fitted,saber tactical front rail fitted etc. Recently i have noticed it sounds louder at the breech end, i changed the orings on the transfer port and the breech oring, but it still sounds a little louder than it used to, any ideas??.
