2 different Swiss K-31's, using 16gr. of 2400, Lee .312-155 boolit. Both rifles always shot a little to the right (2" or so) with Gp-11 and any jacketed HL I tried. So I made the stop coller adjusting tool and adjusted front sights to the right after the boolit load moved even farther right. The front posts are now nearly all the way to the right wothout pushing it over the front of the slide way, and still are 1" to 1 1/2" right. Its as consistent a POI as I can do, but right of the bull.
So, is this common with reduced loads? Would upping/lowering the charge a little help? Other suggestions? Just settle for aiming left and live with it?

Okksu,
What you are experiencing is common. You might bump up the charge -- one of mine likes quite a bit more than 16.0 grains. Perhaps another powder?

Low volisity and shooting to the right is a given with the K31, up the charge a little and you may still have the move the FS a little more right.
I have a 311291 mold that cast a small nose(.298) I use it and 18 of Blue Dot in my K31. The
FS is drifted right so far that the front of the sight is out of the dove tail about .060

HI,
WOW, I GUESS I AM LUCKY. I have had only the vertical poi change which was expected.

At the NCBS 400 yard shoot my boolits impacted much further left than @ 50 or 100 yards. The wind was predominately left to right. Returning the sight to 50 yard sight in required an adjustment back from the left impact also.
