Seras received this rifle, which is assumed to be standard issue for Hellsing soldiers, in the first few episodes of the anime. This was before Walter decided that she needed a sidearm that complemented her superhuman vampire strength.
In the original anime, the rifle had a more black polymer finish and stock, but in the OVA, it was switched to wood. This weapon is clearly manufactured by the Hellsing organization for anti-vampire combat, though it is uncertain who was intended to wield it before Seras joined. The stock engraving reads "Anti-Midians". The actual design is based on the Mauser 1918 T-Gewehr a 13.2mm bolt action anti-tank rifle used by Germany in World War I.
When Seras first joins the Hellsing Organization army, she receives this rifle as a sniper.
Bullets and RoundsEdit
In the first anime series, this rifle was fully automatic, as it appeared to be self-loading. However, in the OVA, Seras fires it exclusively in a semi-automatic manner. Later on in its usage in the anime and OVA, it is used with a drum magazine.
She also used it with a drum magazine later on in the Anime and OVA. The stock engraving reads "Anti-Midians" and gives the caliber of the round as a massive 13.7mm, unusually large for a rifle.
