I've recently started working up loads for this bullet in a .270 wsm t3 in a McMillan stock. Having trouble with it, tends to group two shots together then third one up to 2 inches away. Any suggestions? Also sometimes my seating die (hornady) crushes a ring towards the end of the projectile has anyone else experienced this? Not very impressed with the overall finish to be honest. Hopefully I can work a load out.
