I'm not trying to argue, but the parent case of the 357 magnum would be the 38 special, would it not?
That is a VALID point on that cartridge.
ATST... I've searched many references and NONE mentioned the 8X57 'case' as the parent case.
Check, 8X57 vs 30-06, 30-06 origin and anything you can find.... I'll gladly read.
The 8mm BULLETs were pointed and LED to pointed 30 cal bullets.
The 30-03 was developed to REPLACE the 30-40 Krag.
The 30-06 was REdesigned FOR 150 gr bullets.
That 'summarizes' my research.
TRUTH ! I have NOT read ONE reference (authority) that links the 30-06 case to the 8X57 case.
I'm STILL looking. I'm NOT arguing either. Looking for FACTS.
