Hats off to sea first,just got back from Montana,dusted lots of p.d.'s with 223 and 223 ackley,don't know why more guys don't use it, you just have to be very careful and weigh every charge, double check before seating bullet,my partner wen't through 500 rounds of bluedot loads in his 22-250,he swears by it.he also used it in his 223,and was very pleased, no recoil, you can shoot a long time before barrel gets hot.
