So I drove out to the range today to test out 3 different Foster slugs. Winchester Super X / Federal Power Shock / Federal Premium
Much to my surprise the cheap Winchester outperformed both of the Federal brands with the Power Shock in close 2nd.
What was even more surprising as to how poorly my shots were landing with the Federal Premium slugs. 2 of the shells failed to eject and had been slightly deformed at the crimp end. I have to note that none of them got jammed they just sat half way out of the ejection port with the bolt back ( i was loading 1 shell at a time ).
This is one of the boxes I was shooting today.

I kept 1 slug to cut it open because I was curious as to what it actually looked like inside.

Here you can see a Winchester hull in the middle of the 2 deformed FP hulls


I probably wouldn't have thought anything of it until I discovered one of the wads stuck in the target cardboard which looked like it didn't collapse evenly. At first glance it looked like the "true ball" was melted into the wad.


CAN'T JUST LEAVE IT AT THAT! I GOTTA KEEP DIGGING





Here you can see the new wad next to the deformed wad
It had me concerned for a moment because I'm not sure what kind of pressure irregularity that might cause in the barrel. It almost looks like it wanted to bind up.


Looking closer at the slug I also noticed how rough and uneven the rim and the walls of the slug looked.


I then used the edge of my knife to lift a few loose bits of lead at the rim of the slug



Seeing the results and the inner construction of this "premium" shell will definitely make me think twice about paying the extra $2-$4 per box next time I am ammo shopping. I definitely will not be buying the Federal Premium slugs again, but I would still recommend the Federal Power Shock to any one of my friends. This is just my experience with this Premium brand of slugs.
The shotguns used during the test were: Remington 870 Im/Cyl Beretta A400 Xtreme Cyl
Sorry for making this so huge.
