Looks like I got some barrels not grouping at all, I can call this disastrous...how can I fix it?
I got a Leshiy2 in .22 with a 350mm barrel just in front of the winter. Not much time to learn all the in-and-outs, but overall not bad at all for the games what it is meant for.
Over the winter I got two 500mm barrels from Russia, with a very last train. One is .22 and the second is .25 (this one I didn't try it yet).
My gun range shooting just started recently.
I swap out the original L2 350mm barrel with 500mm, cal .22.
First pellets I shot the AA Field 15gr, 915 fps. For couple days at 50 meters the tightest groups I got about 2".
I was not happy with that, could be the wind is tossing the pellets too much, so today I grab the heavier JSB RDM's 25gr and retuned the L2 for about 930 fps.
Shot them at the range, absolute disaster. I could see the pellets spiralling in the air, there is no group at all about 3-4" radius.
I left home and tinkering what else I can test? Swap out the barrels from 500mm back to original 350mm and tomorrow if the weather permits me back to the range.
What can be wrong with barrels? When I received them, I washed thoroughly with Balistol and polished all with Carnauba Vax.
Just now inspected the Russian barrels with a high power levellers lupe lens, also with a long rod I pushed through all the barrels their pellets.
The original Alpha barrel (or I think it is Alpha) is 12 rectangular shaped rifling, feels like choked at the end, the pellet head and skirt has a full contact.
The Russian 500mm barrel is 6 round shaped rifling and feels no choke, the pellet head and skirt has a full contact as well. The crown is maybe questionable but I need to visit HomeDepot to pick some ballhead brass screws and have a closer look again if I can improve.
What else?
{btw, to add in last second before posting, I didn't washed/lubed any pallets, not the AA not the JSB, just straight out of tins. OK, that may effect with scoring but shall not brake the groups}
