I am going to go hunting in Virginia for deer (.30-06) and the farmer
next door said I could come shoot groundhogs to. The 22lr is sighted in dead on at 100 yards with winchester 36 grain hollow points would these work
if not I have some cci mini mags in 36 grain hollow points would those
work.

Either bullet will work fine for you. I'd use whatever shoots more accurate out of your gun.

Good luck finding groundhogs during deer season. They are mostly in hibernation by the end of October. I use the CCI maxi-mag in my .22 mag. for groundhogs.
