When I first started reloading I had this problem with a 300 win mag and a 22-250. My problem was I was resizing to far. Backed off the dies and 45 years later everythings ok. Good luck. Ed k
My first experience with oversizing cases and case head separations was with the 300 Win Mag also.
I wish I had a nickel for every thing I've learned the hard way and a dime for every time I've learned the same thing the hard way twice.
Wisdom arises from experiences which arise from ignorance.
Learn from the mistakes of others - you'll never live long enough to experience them all first hand.
