Been a while. Had a kid...things got hectic for a minute. Thought I’d give an update/see if anyone else has seen this. Got my DL 22 shooting the 15.89s lights out at around 900 fps. It shoots these very well (1/4”-1/2”) groups at 60yds for quite some time. The best I can get the 18s to shoot with various tunes is about 1” at 50 and 1.5” at 60 (also at about 900fps). I ordered some hades to give them a go. Man. They’re all over the place. In fact, they shoot just about like the poly mag shorts. I’m talking like a 12” group at 50, in clusters. If I shoot a full mag, I’ll have about 4 clusters of a few hits with several ransoms. I went back to the 15.89s and she’s dead on. Everyone else seems to be loving the Hades. I cleaned the barrel n tried again. Same. From 700-1000fps, no dice. This is with the 500mm barrel. Thoughts? Anyone with a 500mm stx having better results?
