[QUOTE="Wyo7200, post: 1044350, member: 82337"] It has been a while since I've been here and I've come across an interesting theory called optimal barrel time (OBT) since the last login. Holy crap its spot on. I've changed my 25/06 load to match a node and shot a four shot bug hole at 100 yards. checked all my other loads and got them to shoot clovers and bug holes. Slowest powder possible that fills the case the most works really well. There is something to it- if you have QL, you owe it to yourself to compare the estimates with the OBT table and theory.
