Can temperature alone get you into danger zone?
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
To achieve the maximum possible accuracy, all variables must be remove or at least minimize.
