Also i was dickin' around with my L691 270wby and 170 EOL's, they were key holing..Thought nothing of it until Barsness reported them flying true out of a 1/10" 270 win. So i measured my twist, 11.75" is what i came up with..Eat a dick douglas!
Out of curiosity did you run any over the chronograph? I have a 1 in 9 twist 270 Win and some of those 170's but adding a 270 Wby has always been intriguing. Hope to load a few this week finally.
