Thanks Rick & Eddy....

BW, I tested this rifle for POI shift when using a pack vs. when using a bipod this winter. I found pretty much ZERO poi shift, but I can definitely hold quite a bit tighter off the bipod.

Here's some targets illustrating a static POI....it made me pretty happy for when I have to lace the boots on tight and don't want the bipod on there.

This group was shot at 600 off of a pack with a rear bag.

And this one was shot off a bipod and rear bag, at 600 as well....

Seems like if you've got a rifle bedded and floated well, with a nice stiff stock, POI shift shouldn't be much of an issue when using a pack or bipod.
