[QUOTE="Lou270, post: 2765761, member: 5352"] Yet another example from Barbour Creek. This is 140 elite hunter out of creedmoor at 700 yards. Another excellent video! 7” before detonation. The yaw effect may not show up in the simulated long range testing by reducing velocity and shooting close range since all bullets yaw a good bit at start. I dont think it is limited to a certain set of bergers as mentioned however most videos are 6.5 and 7 mm video. Maybe other cals do not show same but I doubt it. If the tip was collapsing without the help of yaw it would do it right away not penetrate a ways then collapse nor would it start expansion at different depths at different distance. Drag decreases with decelleration as bullet penetrates but increases with increase of surface area in contact due to yaw which more than offsets it. Hitting bone helps a bunch too Lou [/QUOTE]
