Just curious as to the way you speak of 5.56. Are you speaking from experience in an actual engagement as to the 5.56 M4 being too anemic or is this just assumption?I've never felt safe with 5.56. always felt it was too anemic at distances especially with our M4
There's plenty of people out there that parrot what they hear online as to the effectiveness of pretty much every common caliber that haven't actually tested these claims.
This is not a jab at you as this is more common than not and I can somewhat understand why someone would make that claim without the experience behind it.
