Very cool.
I have read of shooters applying additional lube to their .22LR bullets but I've never tried it myself.

[rookie]

Yep SK / RWS (European) use an oily lube whilst CCI/Federal (American) use a waxy lube

Appears your rifle likes the extra lube as bladeracer indicates

If I change ammo, I usually wouldn’t rely on the results of the first 20-25 shots after changing.

Some say, clean out the barrel if changing ammo ..

Experimenting is fun either way!

Nice looking groups there

Shooting lead is vastly different to high-volocity jacketed.

very true, I am switching the small game hunting rifles from 22LR TO 22WMR due to this reason
