Tuning leshiy 2 chrony #'s let's post em

I bought the 580 for my impact and used the 480 on the L2 also i did modified the lower tube and install it instead of the upper tube will have more room for the grip

Interesting, I have a large Plenum set up, not sure if that will give me enough grip space for the 480cc will haveto do some measuring.

I think its will fit its 2cm longer so it should fit perfectly

The tube swap is awesome. This should be put on the 160 page Leshiy 2 thread. I would have done that first rather than buy the 350cc . I know with the .25 and bigger calibers the extra volume sure would be handy. Maybe EdgunWest has the factory tube end or can order them in. I like the OEM length of pull so I’ll leave mine as is.

Just to re-cap my Nov.08 tune on Leshiy2:

350mm – .22 – 104 bar – 0.7 and 0.5 jets – 16 grain AA Field – Avg=893 fps – full 9 mags in a single fill before fall from Reg.

Today replaced the 350mm barrel to 500mm, same Reg

104 bar 956 fps, the longer barrel jumped the speed about 63 fps

97 bar 932

74 bar 856

81 bar 872

84 bar Avg 887 fps – St.Dev 3.8 and I am going to leave it here for now

This is a standard Reg not a REPR
