I have had great results with the indian creek black diamond strike.
I run two .665 one in an 870 and one in an 11-87.
They pattered extreamly good with h13 heavy shot #6 in the turkey load and also really good with heavy shot dead coyote t shot as well as remington HD BB.
I just shot my biggest coyote to date this past saturday with a load of 3.5 inch dead coyote out of a 24 inch barreled 870 at about 35 yards 16 pellets in the neck shoulder region with a few more spraying hits left and right and up and down.
The dog never new what hit him,DRT with just a slight after flinch.
Ill post pics of this dog in the shotgun thread once i load them to the computer.
I have been so impressed with the indian creek chokes that i bought two different constrictions a .690 and a .710 for my SP10,i think the .690 will make a fantastic turkey choke and the .710 i hope works out real well with remingtons HD BB load for the 10ga.
Again i will post results in the shotgun thread once i pattern the 10ga.
