Home Forums Hunting & Shooting Hunter's Campfire Embrace The Truth - Catastrophic Gun Failure

I went back at looked at my notes, my final loads for my hunt were 85 grains of H-1000.

It is over the published data of 83 from Hodgdon Data Manual.

I worked up from 10% below max and worked up the final load in half grain increments looking for accuracy (also potency) since I was hunting for moose in Alaska with Griz running around. There were no pressure signs EXCEPT FOR THE F UCKING GUN EXPLODING in the cases compared to the 83 gr load (no blown primers, splits, cracks etc.). I even had two other experienced reloaders look at the cases.

Also, since this was a single shot, I was not seating the bullet as deep, allowing for more case capacity… but I was not engaging the rifling. My loads did not exceed SAAMI PSI for the 300 win mag. They were at max but not over.
