Was doing some reading about how slugs like a clean barrel. Decided to try that and use a really loose hold. Also decided to weight sort. These are very inconsistent! But a big improvement from what I was getting initially. One thing I noticed was it would either vertically string or there would be a relatively tight group and then a flyer. Like a country flyer. This just confirms to me that the tune is not optimal for this pellet. Makes me curious about the new 0db tuner for situations like this, but I'll just waste these on some steel or save them for another gun down the road. The last card I shot tonight was the queen and the upper left spade was with the AEA 18.3s.
