[QUOTE="AZShooter, post: 1013077, member: 5219"] Michael, German Salazar wrote about the small primer in the 308 in his blog. Here is paragraph that sums it up: "Simply stated, the small primer in the .308 case is at the low end of acceptable ignition under ideal conditions - and conditions are often not ideal. As ambient temperature drops and especially if ignition systems are modified (uselessly, I might add) with lighter firing pins, ignition reliability declines. A system which is marginally acceptable under ideal conditions will then begin to produce hangfires and misfires. In many cases, when shooters used the Remington small primer cases as a full-length .308, this is exactly what happened. Heavier powder charges and slow-burning powders further add to the difficulty of ensuring reliable ignition. With the typical Palma load of 46 grains of Varget, a moderately slow powder, I will venture to say that many small primers will be inadequate to ensure adequate ignition under all environmental conditions." I would think the 260 would react in a similar manner.
