I read an article that the cocking arm of the 125 will bend at the SAS location if the gas ram is too powerful.  I pumped up the vortex to 115 bar only and the 125 sniper is shooting at 840+ fps with 19.4 gr.  That is good enough for me.  I have two type 2 vortex gas pistons.  I will try another with 125 bar and see whether the mv improves.  Actually, it is quite dependent on the sweep volume of the compression chamber.]]> Sat, 18 Jan 2014 08:06:44 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=90&PID=479#479 www.kiwiairgunners.co.nz/forum_posts.asp?TID=90&PID=473#473 Author: nunga

Its a MOD 125. i am looking at 150+ bar or around 2000 psi still working out the fine details on the piston seal inside the ram.

@Nunga. What model of Hatsan do you have? Regarding your home-made gas ram, what is the builtin pressure? I suppose your gas 8ram is pressure adjustable, just like the vortex gas pistons from Hatsan. I installed a xman xl nitro piston into my Hatsan 155 with the ram body in the piston. It shoots at 900+ fps with 19.4 gr pellet. It is the most powerful springer in my lineup.]]> Tue, 14 Jan 2014 15:02:38 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=90&PID=472#472 www.kiwiairgunners.co.nz/forum_posts.asp?TID=90&PID=471#471 Author: nunga

Hello and welcome, I will be interested in your gas ram conversions on your Hatsan springers. I am in the process of converting my Hatsan as well with my own home made ram. so any information you have on this is very welcome :)

Mostly plinking.  I have my own range.  Maximum distance 80 metres.  Occasionally, I do keep pests at bay; pests like rats and starlings.  My favourite is a locally made pcp with a 24" LW 0,22 barrel.  The silencer was made by UK Neil (imported).  I can hit 5 shots at 80 metres 0.2" ctc with it. Next in line is my Diana 54 0.177.  It is perfectly tuned by yours truly with a Vortek PG2 kit and a 135 wire.  I also installed an O-ring piston seal.  It is shooting at 924 fps avg with 9.7 gr pellet.  It is almost on par with my PCP.

Welcome along mate, what sort of shooting do you get in where you are?]]> Sat, 11 Jan 2014 17:10:22 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=90&PID=468#468 www.kiwiairgunners.co.nz/forum_posts.asp?TID=90&PID=467#467 Author: havenofear

Hi everyone. I am new in this forum.  I just wish to learn from fellow forummers on modifications of spring-based (either spring powered or gas rammed) springers.  I do all the tuning myself and all my Hatsans were converted from spring to gas rams. 

Will share my experiences in the modifications in the coming months.
