I question anybody who exhibited a blind bloody minded attitude and I don't give a damn who you are or what station in life you hold. Plenty of my bosses will attest to that. What on earth makes you think you are so special that you can tell a story, that you were not there to see and think it is exactly as told. As has been said the rifle being PF is irrelevant if it was a manufacturing fault but you can not see or acknowledge this. So I am more questioning your rationality and clear thinking abilities. You mention your Critical thinking skills, well sir I see no sign of these skills what so ever. We or at least I have not asked for the make, just exactly what part of the rifle/bolt failed and why it failed. To say it failed as it is PF actually tells us very little.
I use to prefer PF as posted but now sided with CRF for DG but this does not blind me to the faults of all, like good yourself appears to be. I suggest that this PF failure you talk about, without describing why it failed due to the push feed operation, is suspect. That is, it could of happened to a CRF with the same faults. So I suggest you get over that, acknowledge you have been carried away with a story you that was told to you not seen by you. You probably feel a great sense of loyalty to your mate, no shame in that, however I would advise caution taking every thing said by a mate as gospel. All have a tendency to change a story, not necessarily done consciously. The other thing is peoples recall of stressful events is very rarely accurate in detail, sometimes in major parts as well. Not done deliberately just the way the human mind works.
