I can't use lead in the area I hunt coyotes in so I use the heavier than lead non toxic Tungsten alloy shot. It works much better than lead but I would still be using lead shot if I could. Lead BB shot works pretty good on the small coyotes that I hunt.
The heavier and harder than lead Tungsten alloy shot in sizes #2, B and BB are devastating on coyotes.
I have taken the shot out of the factory load 1-1/4 oz and 1-3/8 oz HD, Heavyweight and Xtended Range loads that I bought on sale when they were being closed out.
Today I just opened up 80 Winchester Xtended Range Hi Density 3" 1-3/8 oz B shot loads.
In 26 of these shells the fiber filler wad that is 3/8" thick was sitting at a 45 degree angle or sitting side ways in the wad. So some of the filler wads had shot on both sides of it with some shot sitting on the bottom of the shot cup..
Out of these 80 shells some of them had buffer to the top of the shot, some had very little buffer and some of them had no buffer.
I did count the pellets in 4 of these shells and they all had 82 B shot pellets in each shell. I weighed out some 1-3/8 oz shot charges and I got 80 to 81 pellets per 1-3/8 oz shot charge according to my scale.
These are the 3" hulls and the fiber filler wads that I removed from the plastic shot cups.
This is the Winchester Xtended Range Hi Density B shot that came out of the shells. This shot really looks good to me.
In this picture the silver looking shot is the Win Xtended Range B shot. The darker colored shot is Federal Heavyweight #2 shot.
It looks like there is right at 59 pellets per ounce with the Winchester Xtended Range B shot and 61 pellets per ounce with the Federal Heavyweight #2 shot.
I just found some 3" 12 ga 1-5/8 oz Heavyweight shot loading data in the RSI Heavyweight Shot Reloader's Guide Vol 3.
I reloaded 100 3" Federal hulls with 1-5/8 oz of Rem HD BB's and now I plan on reloading all of the Win Xtended Range B shot in 1-5/8 oz loads in the Federal 3" hulls.
There is right at 77 pellets in the 1-5/8 oz HD BB load and there should be right at 93 pellets in the 1-5/8 oz loads of Win Xtended Range B shot loads.

Watch the above video. The coyote in this video was shot with 1-1/2 oz of Rem HD BB shot.
