Although I basically agree with Cinders, I would recommend that you buy an extra-high front blade for your rifle. Holding deep is only practical if you are always using the same rifle at the same distance with the same ammo.
Change one of those three, or shoot more than one rifle, and it becomes totally confusing. Sooner or later you are going to want to shoot accurately at longer distance than 25 yards! So you will want to have the POA in the adjustable range of the sight, to be able to zero it for a specific ammo. ALL my Mausers (German, Swedish
, Brazilian
, Argentine) have ended up with a taller front blade for that reason.
