Let me say one thing, you haven't done a work up taking loads off accurate shooter. They were for more than likely a custom gun. I have the same barrel and at 30.2 grains of varget I blew 2 primers. So what it comes down to is you need to learn how to work up a load and documenting everything you do to reason out what you haven't done. We don't know how you prep your brass. What press you are using. what dies exactly, what are you weighing your charges on, how do you seat your bullets(what type of seater), How you determined when you are touching the lands, How much run out of the bullet after seating, how much neck tension etc. I am in no way picking on you but loading isn't just selecting someone else's load and saying the gun wont shoot. One other thing, what are you shooting off of and have you let someone that can really shoot try it to be sure.
