Just got off the phone with my son. He's doing another pesting hunt for pigeons. Got about 300 from yesterday evening and dark plus today. But he is trying lubes(several) on targets and now on birds. Thinks he has gained from 70 to 90 yards good kill grouping. Using WD-40 silicone seems to do the trick. Says he may have a little too much on as it gathers at the stripper. He and his GF have twin guns Brocock Bantoms in .22 with NightForce scopes with green light at dark. Said there are clouds of starling in the evening but they don't like the green light.
