Picked up a couple packs of deadmeat 125grs recently. Somehow I must have overlooked the fine print in the listing on one of the packs and ended up with the original deadmeats. The second pack I received are the correct v2. Just curious what the differences are? Right off the bat I notice the collars and ferrule are different. I guess my main question is were there issues with the originals that led to the release of the V2?
