5.45 & 5.56 SBR - SPINNER CHALLENGE
This InRangeTV video details a 'Spinner Challenge' designed to test the effectiveness of different barrel lengths and calibers on a spinner target at 50 yards. Expert instruction highlights the significant impact of sighting systems, particularly iron sights with short sight radii, on accuracy and the ability to consistently spin the target. The challenge demonstrates that both 5.45x39mm from a full-length AK-74 and 5.56x45mm from an 8.5-inch SBR can successfully spin the target, with sighting limitations being the primary obstacle.
