I have loaded Hornady, Sierra, Nosler, Speer, Winchester, Remington, Barnes.... with no pressure problem hot or mild in any rifles I own. Disregarding Brownell. Sorry, I speak from experience.
Sorry heym06 but you are missing some other varibles other than jacket consistency.
I guarantee that the OP didn't heed to 10% below start loads, and that's the reason for the blow ups.
