This is the SR-330AM used by the EDF. For all who don't know the AM stands for Anti-Material. This means that while the SR-330AM is perfectly capable at hitting flesh targets, it excels at destroying heavy stuff like punching through walls or armor. The SR-330AM is the second heavy sniper rifle to be used by the EDF, the first being the M-449 30 cal AM rifle, but is used more in the field because of its smaller bullpup design.
The actual ammunition is actually lighter as well. The SR-330 uses a custom round that as been dubbed the "60"cal bullet. It's a thicker, but shorter then a 50 BMG to fit in the smaller mag. In the field it has come to overpass the performance of the 50 cal. round, flying farther and faster. The SR-330AM's 60 cal round actually comes in to different types... There's the standard round that comes in Anti-personnel (Shredder Rounds), AR, and incendiary. Then there's the fin stabilized, discarding sabot round. This offers greater performance then the standard round but is used less due to the fact that the extra powder to make the shell go farther increases the width of the cartridge, which lowers the amount of rounds in the magazine (plus they're super expensive.)
