POI change?

[shoot2reload]

I've seen repeated references to loosening of the Action Screw for breachplug removal causing the point-of-impact to change. I'm showing my ignorance here, but I can't seem to conceptualize how this happens.

Also, could somebody point me to a thread that has details on the third pillar screw mod?

You guys are awesome! Thanks in advance!

While Ive never experienced this with my ML II several have, but I always bed my guns before I do any range work.

A third pillar is added 3/4" from the front action screw.

All the info is kept in the Tips & Hints Section at the top of the page. Mike

Basicly when you loosen the rear action screw to remove the bolt and then torque on the action to remove the breechplug, the action can shift in the stock. Then when you fire afterwards the action has to "settle" in so your POI will shift and then maybe come back to the original spot. Basicly the squirm of the action in the stock during that micro second of recoil before the bullet exits the muzzle causes the shift. Bedding can minimize this and the third pillar is also a big plus.
