Poi Shift

[joeb33050]

Yesterday I was shooting the Competitor pistol at 50 yards, 12.5 AA#9, was shooting 311299 then switched to 31141. The point of impact shifted ~3" to the left at 50 yards, and the only change was the bullet. Picture of the target may possibly be attached, if I'm lucky.
I've never seen such a thing, certainly sometimes the poi shifts with a change in x or y, but not such a reliable big shift. I'm surprised. Are you?
Thanks;

I'm not surprised... I frequently get a change of POI simply by changing powder...

POI change is normal. That's how you hear guys wanting to change loads with fixed sights and why they cuss.

But looking at those targets, I would go back to the 311299 myself. That's good shootin Joe.

Bedding issue? Barrel touching stock? That's what I'd look for in a rifle.
