I took my .223 to the range last week and started at about 40 yds (sighting in again).
Best group I could get outta the stupid thing was about the size of my fist. I was dissappointed. I was only using factory winchester bulk ammo but 3-4" are you kidding me.
I got got frusterated and just moved target to 100 yds, and it cut a 5-shot ragged hole that was well under .5 MOA.
Having under $300 in the rifle (not counting scope) I was singing at the top of my lungs (almost).
But why the poor groups at 30-40 yards? Maybe it was me?
Rifle is a savage/stevens 200 that has been glass bedded and barrel channel opened up, and panted that aweful stock
