Review: Nerf Zombie Strike Sledgefire (grey trigger)

Now for a different Nerf line, here's a review of the Zombie Strike Sledgefire. Sorry it took so long to get this review done.

The Sledgefire was one of the two blasters in Zombie Strike's first wave back in late 2013. Like its partner the Hammershot, the Sledgefire is a completely new design rather than a modified version of an older blaster. Unlike every other Nerf blaster though, the Sledgefire uses shells to allow for fast reloading of multiple darts. This concept has been around for a while, primarily from Buzz Bee, but has had mixed opinions. Some like the novelty/realism factor of the shells, while others hated how they drastically increased reloading time. So how does the Sledgefire stack up as a shell using blaster?

Full 2013-2014 Zombiestrike Line, My Opinion & Conjecture

NOTE: Now that all of these blasters have been released, all of this conjecture and speculation is now irrelevant.

So my blog feeds and FB have just been saturated with posts on the full Zombie Strike line for 2013 and 2014.
Original credit goes to io9, but I got my first info from Basic Nerf and FFA (links left).
EDIT: Release dates in Aus thanks to UT.
Anyway, keep reading for all the pictures and my opinions of each blaster.
NOTE 1: Much of the following is conjecture and may not be true. DO NOT USE THIS ARTICLE AS A RELIABLE REFERENCE REGARDING BLASTER PERFORMANCE OR MECHANICS. Instead use it for thought provocation and inspiration, as well as eyecandy borrowed from other sites. It could be that everything I say in this article is completely and utterly wrong.
NOTE 2: I have not actually participated in a HvZ game, but I have read a number of articles describing tactics and all that. Do not use this article as a reliable HvZ reference.
NOTE 3: In the HvZ Practicality sections, I am making the assumption that the blaster being described is the only blaster you're using, for arguments' sake. With multiple blasters there's so many possibilities that describing just a small fraction for just one blaster would take a novel to fully describe.
NOTE 4: It has been said by several people in HvZ that having a good blaster does not guarantee survival. Many have said that tactics and skill are far more important, and the same applies to standard Nerf wars. Thus this article is written with the assumption that the player has a reasonable amount of skill, but not so much as to make them an expert and able to survive with any blaster they are given.
