Leshiy .25 350mm – POI shifting
Hi,
I test all PCPs that I receive in laboratory-like conditions:
I must admit than many high end airguns and barrels failed my test (9 groups, 5 shots in each group, 50 meters). By failure I mean any anomaly in grouping during 45 shots. The mean group size should stay below 20mm. And yes, I can shoot:

This is what I expect from a high end airgun. My best group was 3.5mm CTC at 50 meters so you can just imagine how small my error can be.
This is how I tested Leshiy (the doors were opened during testing, no worries 😉 ):
In the beginning everything was quite acceptable at the distance of 50 meters:
Then, after maybe 30 shots the group moved 3cm to the left:
I tested that at 10 meters and POI was shifted by like 6mm. After barrel cleaning everything was spot on again. It looks like I need to clean the barrel every 30 shots or so. Something is simply wrong with that LW barrel. I may just guess that it is just me with that problem. Am I right?

Best accuracy is normally given by a free floating barrel design and certainly on the Leshiy there can be external factors troubling accuracy.
But isn’t the Leshiy more of a hunting tool with a “kill zone” accuracy?
No, not again!
I am jealous of that shooting range! I would agree that it sounds like a barrel issue.
I wonder if there are any decent 6.35 barrels from LW.
I think it gets dirty really fast and then the precision goes south. The choke is rather light but the lead accumulates in the middle of the barrel. I will try to polish it with Autosol.
I’ve been testing a couple of 6.35 LW barrels recently and neither of them liked JSB King pellets :sadn: .
Looks just so strange… change that barrel.
Yeah, it’s SWFA 3-15×42 FFP. It’s very unlikely the scope or mount (Vortex Cantilever) are bad.
As of the groups – I selected the best ones. Here is what happened after like 40 shots:
Low precision and shifting.
Wingman, you are lucky that you ordered Leshiy without LW barrel 😛 .
I suppose scope is failure-free? SWFA (?) should be good. My first thought was turret/reticle failure.
Never seen such a shift before on any airgun, grouping is fine… just shifted. Never had an effect like that in any of my pcp (AA, BSA, Daystate, EdGuns).

No, Wingman shoots below MOA at 50 and 100 meters.
