Well I gave one of my sons one of my 95 hatsans so I took the plunge and bought a 135 25cal. Now i have a spring 25 to go along with my 25mrod when I am too tired of pumping . Can't wait to see how it shoots'
I'm using Krytox lube in my H135 so when I disassembled my gun my warranty went out the door.This lube is extremely slick and used it as I would use moly behind the seal used less than you would use moly and decided to use as an only lube and made a long tophat to prevent spring twang when shot .It works great then my spring broke and had to use a 44 coil spring in place of my 47 coil that broke at the last 2 coils on spring guide and saving that spring for a backup.Hatsan doesn't have parts available in the usa yet.Umarex has the 44 coil spring in stock for their walther falcon hunter series gun that I use to have.If you ever have any trouble with the gun just go to Hatsanusa or airgunweb and contact Rick Eustler as he is the warranty Rep. for Hatsan he's quick on his replies and service.Whitefang has flaring tool for FTT's and other .25 caliber if pellets seem to fit loose in barrel as mine is I gained up to 50+ fps when flared.Last time I chronied my gun with 20.06 grain it's shooting between 855/862 fps.Mike my buddy was shooting it at 40 yards at a empty tin can and watched his expression his eyes opened wider and mouth opened he said man this gun is fast.Been trying to test my gun at longer ranges but my scope isn't holding zero very long.Think you'll enjoy yours.
No I have no comparison on the 2 springs, the kytox is so slick in the compression tube and the shot cycle is alot quicker and added a piston weight slug to make up the lenght lost.My 47 coil spring broke.Just trying to say that the 44 coil will work if needed with some spacing ,probably wouldn't need it if you want a calmer gun minus the spacing.
