The setup: 223 Remington 700P LTR, 75gr AMax, Lapua Brass, H4895, Wolf primers Dillon 550b, RCBS dies
Round one: 22gr to 24.5gr in half grain increment coal 2.26 100 yards 5 shot groups new brass
Round two: 22gr to 24.5gr in half grain increment coal 2.425 100 yard 5 shot groups Lee Collet Neck sized
Question: How can accuracy improve while standard deviation increase?
Overall velosity was lower at every load on round two and group size smaller.
Is this shooter error?
