Well I got out to the range on saturday. It was quite windy here so I didn't bother putting a target out at 100 so at 50 yards the first 5 rounds went pretty much through the same hole (this is just using winchester 550 pack ammo) after ten shots I had one ragged hole with a group that was .1 center to center. I'm looking forward to getting out more with it. I suppose I will have to try some target ammo, but I built this rifle for varmint hunting so I will mostly stay with the high velocity loads.
