[Starligsniper]

With the new m4 magazine. What are the heaviest NSA slugs
Altaros slugs
Zan slugs that can be run

Go aftermarket for magazines. They seems to cycle better for heavier slugs. Also for the super heavy ones just don't fill the magazine full. Just put 5 to 10 at a time as the weight is too heavy for many of the magazines made.
