I think that's copy a message sent to Jim Ward of Warbird Turkey Calls , Jim posted that up in our 10 gauge section- Jim also has a good working relationship with the good folks at EM
The performance of the 10 gauge EM Magnum Blend load is up for eager anticipation by 10 gauge enthusiasts , I can tell you that if it shoots anything as good as the EM #5 HS load it should perform very well -
EM has perhaps more 10 gauge load offerings than any ammunition company , I can see where they have goose , coyote , and now it looks that they have a very serious contender to be the best 10 gauge turkey load -
