Can temperature alone get you into danger zone?

[QUOTE="Desert Fox, post: 158460, member: 396"] When I developed the load for my 308, I settled on 45 grains of BLC-2 to propell the 168 grain Nosler Comp bullet at around 2750 fps. Accuracy was excellent and pressure was normal. I thought, I found a really good load combining accuracy and velocity until one day last summer when I got into trouble shooting this load in a 105 degree ambient temperature. I pretty much beat-open the bolt handle, using the plastic handle of a large screw driver. So my question is...can temperature alone get you into danger zone? or is the case design, brass thickness, chamber tightness has a lot to do with it? What's the velocity increased (fps)expected per degree rise in temperature? Enquiring mind want's to know. RJ [/QUOTE]
