Since June 6 I've been able to use these slugs on prairie dogs, ground squirrels, starlings, and a few other varmints. Chrony says 935 fps average in the FX. I've shot varmints out to a ranged 95 yds. Performance on PDs and ground squirrels is at all ranges is very similar to HV fragmenting HP .22 LR bullets. Excellent accuracy, flat shooting, far superior performance to most pellets for hunting and varminting. On top of it all, better value than any other slug I've used. For me, these are better than Christmas morning!
