Migra Ammunition Stack Load Features The Migra Ammunitions Stack Load combines two shot sizes #2 and #3 in a single steel shotshell so waterfowl hunters do not have to guess which range a flock will present. The patent-pending stacked-load technology layers the shot column to maintain a consistent pattern rather than letting the two sizes separate in flight. A 1515 fps muzzle velocity keeps the load carrying energy downrange supporting clean ethical kills on both close decoying birds and longer passing shots. The 1-1/4 oz payload in a 3 hull gives the shell enough shot volume to back up the added versatility of the dual shot sizes. Migra shells are manufactured in small batches using premium steel shot with no fillers a production approach intended to hold patterns and velocities consistent from box to box. The steel shot construction is a non-toxic choice suited to waterfowl hunting regulations across public and managed lands. Each box holds 25 rounds giving hunters a practical supply for a morning or evening hunt without over-committing to a single shot combination. For waterfowl hunters who want to carry one versatile load into the field instead of switching shells between decoying and pass shooting the Migra Stack Load is built for exactly that job.
