I bought a Hatsan At44-10 bought a year back. It is an awesom rifle. I did not shoot it for 3months, when i tried to shoot it it would not load, it was rusted. I searched the net to find out how to strip the rifle and that is how i got this forum. I managed to strip it polish the hammer, clean it, all tips from this forum and reassemble it, thanks to this forum. I managed to lose one o ring on the transfer port so i have to get another before i can put everything together. Reading through the forum i read about changing the hammer spring for a stronger one, what will i gain. Where do i get a smaller transfer port, will i loose power to the barrel. If i adjust the hammer spring will i gain power and loose accuracy. I live in Rustenburg.
