Leshiy 2 REPR tuning

[260Shooter]

I have had my Leshiy 2 Raven .22 cal (350mm barrel, behemoth moderator) for a couple months now. I am struggling with groups across numerous projectiles flying at velocities that I have had great success with out of my other pcp rifles. I will get a consistent 5-6 shots half moa and then a couple fliers 1.5”-3” different poi in random directions at 30 yards.

I have checked all scope hardware torques, made sure moderator is secured tight onto the lugs, made sure all ammo is seated into the mags well free of dented skirts, and cleaned the barrel. SD’s across the mags are consistently 5-9.

Any suggestions on where to start with further trouble shooting?

I would look at the barrel right now. I've had some .22 L2 barrels that weren't very accurate ootb and would throw a lot of pellets like you are describing. A few runs of JB bore paste on a mop through the length of the bore cleared away the issues and really tightened up groups considerably. These were the LW barrels.

I will give that a try ASAP. Thanks!

What is a Reg and the jet numbers?
If the barrel crown is pristine the air blast at the muzzle can still confuse the projectiles. But that is the 350 barrel attitude ... same tune without toutching anything but put a longer barrel and you would get an eye opener

To be honest, I am unsure of the jets in the rifle. It is the factory “Raven” version of the REPR ordered from Edgun West. I have been adjusting the reg while shooting across the chronograph to test for favorable velocities by way of group size and velocity consistency. Have used JSB 14.35, 15.39, 18.1 & 25.4 grain as well as the hn 21.14 and the hornets doing the same with each. The flier phenomenon has been across all brands and weights.

Yesterday I noticed a crack in the plastic housing that holds the spring/gearing for magazine indexing. Looking at some of the lead in the behemoth when taken apart I am suspecting clipping from improper indexing. Brian from Edgun West has been super helpful and is getting me the part asap for repair.

Hopefully this along with the bore paste will give some answers!

Are you able to shoot it without a moderator?

Yes I can. I have not tested the symptoms like that yet, but will. Good point.

Canada here, all kind of moderators prohibited, so yes, the moderator doesn't help.
You have an agressive air blast at the muzzle = dwell time is long for a given Reg pressure !!!
