It takes courage to do it Moebedda, but if you're game here's how you do it.

You need a very large C-clamp, a piece of 4x4 lumber as long as the barrel, and three short pieces of 2x4 lumber. You put them all together like in the drawing below (please excuse my crude drawing skills). You may want two additional short pieces of 4x4 to rest to long section on. It makes it easier to work with the C-clamp.

Put a very slight bend, shoot it to see the results, and bend it again if needed. To raise your point of impact you will want to rest the barrel on the cradle with the sight up, so the "belly" of the bend is on the bottom of the barrel.

EDIT: It's handy to have a long straight edge to check results. Put it on top of the barrel before you start. If the barrel is straight it will have full contact along the barrel. Check it again after attempting a very slight bend to see if there's any daylight between the straight edge and the barrel. It will give you some idea of how much bend you're getting. If you can see just the tiniest bit of daylight you've probably done enough. If it's a round barrel it helps to put a "V" notch in the 2x4s to cradle the barrel.



SECOND EDIT: Hey Moebedda, I got to thinking about your problem and am wondering if you can remedy it by tinkering with the bedding. Is is a full stock or half stock? Is the barrel pinned or held by wedges? Round or octagon? It may be that a shim (something like a one inch wide strip of plastic cut from a milk carton) placed under the very front of the barrel channel will raise the POI a little.
