finally got a decent 50 degree day to try my newly fabricated case deflector with Tulammo 55 gr. ammo-it worked ! (80 rnds worth)no more getting whacked in the face!(shooting left handed that is ) you can see the defector in the gallery by the way. Total round count is at 800 all brands- PMC, Remington , PRVI Partisan, and Tulammo,the russan stuff did produce FTF the primer was simply dead , having been hit hard 3 times -but at 3.79 a box before shipping oh well !
