This is an improved duplex load for migratory birds. Unfortunately I still remember hunting waterfowl with Imperial SSG's.... nothing takes them out of the sky like lead and I can't say I have found anything I am truly happy with since its demise in '99.
Alas things keep changing….this improved load is among the fastest, hardest hitting load in it's class and was designed for the heavier stouter birds. Bring on the honkers…..
