P08 with rifling in poor condition

[gcaivano]

I have observed that when the rifling is not in good condition in general the p08 tends to group the shots to the left, then by lowering the pressure I achieve center groupings (In this way the bullet takes the rifling). Has the same thing (general grouping to the left) happened to you? Do you have an explanation about why it is always on the left with normal pressures and rifling in poor condition?

Did you test this with freehand shooting?

Normally speaking they are accurate, even with a worn out bore. Sounds more like a shooter/sight alignment issue to me.

Barrels with right hand twist rifling shoot to the right and guns deigned to be used at great distances have sights that take this into account. Artillery Lugers, for example, have self compensating 800 meter sights.

Thank you, I'm talking in small distances of 15 meters (also as they have right hand twist tends to go to right not to left) .. also with the stock happened to me and changing magazine ... I'm reading and reading but nothing related ... of course mine's base on real experience after testing a lot of pistols with very poor rifling .. perhaps as you mentioned is my problem ... but with good rifling I have no problems at all...also after decresing the qty of powder I move to the center... perhaps high pressure and poor rifling get to the left with right hand twist...I don't know

Classic when being right-handed, due to poor grip, the index finger pushes on the left
This can of course have other causes.
