Today, I went to zero my new Rossi slug gun and I spent over $50 on 4 boxes of Remington premier Core Lokt Ultra sabot slugs. They seemed to be all over the place at 50 yards and I had 2 out of the 17 I tried to shoot misfire. I checked the primer and they had a dimple in them although they were kind of small. I compared one of the misfired slugs to one of the fired slugs and I noticed that the primer seemed to sit deeper in the misfired one. I looked at the end of the shell from the side and could see the primer in the spent shell but not the other. Has anyone else had quality problems with these sagbots? I'm about positive that I will switch to Winchester partition golds or Hornady ssts after this. I just know that if I stayed with the remintons, I'd get a thirty point buck 20 foot away and get the dreaded click.
