Well, I went for the cheaper option first... Napier Pellet lube. And so far, it's working. It hasn't been cleaned in 80 shots and there's been no flyers. Despite 3-6" of wind every pellet bar 3 in the 30 shot was touching a line at 55. MV was more consistent as well, albeit only 10 over chrono were fired.
Another Steyr user is using another lube with good results also.
There was a POI and MV shift down. Don't know if that's gun or what... don't really care to be honest...
Oddly, when pushing a barrel through a spare barrel that felt baggy indoors with sized pellets, it was reasonable tight. I could blow them down the barrel indoors, outdoors in the cold i couldn't. Could be another reason why some guns run slow in winter... tight barrels?
Dunno. Will see how the lube goes as I go...
