Wait until the old boy beside you touches of a 300 Weatherby that had about 10 grains of 2400 under a full load of 4350. Even the Weatherby action couldn’t keep that bolt in. It was ugly, check your equipment folk’s!
I had a Remington box of 7mm Remington magnum which I used in a model 700BDL.
The first round out of that box locked up the action. I had to beat it open with a block of wood. I phoned Remington to let them know but never could get anyone who cared. I got tired of making long distance phone calls and just quit.
It didn’t do any damage to the rifle but I figured a few more like it and it would. I probably still have what is left of that box somewhere but haven’t seen it in years.
