Tested 5 types of ammo today to determine which will be used for final sight in. shot at 52 yards @ 93 degrees and 90 percent humidity. didnt mike it out but i am pleased. bulk pack winchester high velocity hp is my choice. best groups came with superx solid pts (as always), but i dont use solids for squirrels. i will sight in next thursday at 40 yards for next weekends hunts, hopefully the humidity will be lower. this gun always shoots great but the fine crosshairs on the little leupold 2-8 sure makes aiming more precise. i dropped the trigger to below 2.5 lbs and it is a little light but i will get use to it before long . first group is 5 shots and the second group is 10.
