But is it claimed potentially possible pressure abnormality likely in this situation?
I doubt it.
The person had no data to support his claim on this particular point. He was talking theory and took the position that it was best to not take a chance. That was on SigTalk.
I was hoping that you would weigh in on this point.
John Linbaugh told me years ago that in testing load data in pressure barrels for the 475L that rifle primers could increase pressure as much as 10,000 PSI without a corresponding increase in velocity
10K PSI and no change in velocity?
Not sure I buy that. I'd like to see the data and which variable correlate with the difference.
Were these alleged difference with using Magnum Rifle Primer?
