can you point me to where you heard this. would like to read about it, 788 action stretch? isn't a mark 5 acton a rear lug locking bolt and all there cartridges are very high pressure.


The Mark 5 has multiple locking lugs but it is a front locking action. Bolt compression seems to be the culprit.



that came out wrong when I typed it I was referring to the multi small lugs. saying rear locking lugs causes bolt compression and action stretching is far left. that's like saying a 1 piece base stiffen the action
