I found out that 78grs of 7383 powder behind a 180gr Berger hp will destroy the rifle in 7mm-300 weatherby.

What cartridge are you talking about?

There is a IMR 7828 but not a IMR powder of the number as far as I know.

Now 86 gr of 7828 is the max load for the .300 Weatherby and a 180 gr bullet.

Please check your data.

How did it destroy the rifle? This looks like a max load for a 7mm-300WBY, but not overly dangerous.

If it was a 7mm WBY, that is a different story.

What happened?

Don You are right, I used IMR7828, never heard of the other.

A 7mm-300 weatherby is a 300 Weatherby necked down to 7mm approximating a 7mm STW in Case capacity. IMR 7383 is .50 Cal Spotter powder which burns like charcoal at a rate like IMR 4895. I found this out later.

Using a non-canister powder is an invitation to disaster, as you found out.
