Shot them today, with 20.0gr 20.5 and 21.0 of 2400. 20.0gr produced a pattern lol, 20.5 was a little Better. 21.0 was a tad better. I was using WLR primers. Do you all have any powder recommendations?
Try 16 grains of 2400 instead. That's a load mine loves for accurate soft shooting at about 1600 fps.
