Hatsan 135 vortex .30cal

Hey guys still not shooting right unfortunately i feel like the scope is good now and i have put more shims in to the breech to make it even tighter, done some pellet testing on the barrel and its really tight at the breech end, where its been pressed in to the block 3 areas are worse than the rest one is from the barrel being bent so i am trying to lap the bore now has anyone got some ideas on what i could use for cutting compound i have auto soul but i would think i would need something with abit more grip in it ? cheers

Hey guys just a update fully taken the scope apart as i could not tighten the front lens without completely removing it the scope is a Hatsan scope i feel like they made up for there average tolerances with a heap of glue on almost all the threads everything had rattled loose so i put grub screws in the rear lens to stop that moving lock tight just was not enough front lens has been removed and lock tighted prettymuch everywhere i could so that should be good now and i also to two brass rods in under the spring that sits under the turrets as it was just sitting there and no doubt it would be working its way around with the recoil really hopeing for some good results but if not i at least had to try will test it over the weekend and see what happens hopefully post some decent groups :)

Email me william.mascull@gmail.com I should still have some. I'm in Chch most days so could meet to give you some to play around with

Well you might be on to something there man i just checked mine and it moves in all directions that wouldnt be helping at all

Yeah in hindsight i would of gone for the .25 for pellet selection i would of easy put 500 plus pellets through my gun sometimes it shoots good sometimes it does not when i clean it it will shoot good for awhile i have read this is a common problem with big bore air rifles normally from a poor finish in the bore which results in lead fowling so i might try polishing the bore some more and see how it goes at the end of the day i dont have anything to loose in the state it is if in doubt ill get a new barrel eventually 

hey guys got the barrel straight used a square looks pretty good gave it a really good clean inside and a polish with some light metal polish first 20 shots were really good grouping almost on top of each other and then it just went to sh*t pellets tumbling all over the show could i just need to put more pellets down the barrel try lead it up abit ?

the barrels are short for a reason, the less time the pellet spends in the tight barrel the less the pellet will slow down and the faster it is...only problem is the pellet does not spin as fast so probably not so accurate over longer distances
