I also saw positive results with my Handi .30-06 with forend modifications. I sanded the barrell channel to clear out any imperfections, enlarged the barrel mounting stud hole so that the forend will freely fall off on its own, which also provided a comfortable seating area for the "O" ring. Finally, I used a piece of weather stripping 1" from the end of the forend to reduce barrel vibration. The results are now consistant groups in the 1" range at 100 yards.
