I own a 870 and 11-87 Remington 20 gauge synthetic shotgun and purchased a few boxes of SST Hornady shells. I noticed that out of the box, some shells the tip is right to the end of the casing and some are at least a quarter inch away from the end of the casing. I can actually shake the sabot slug so that it moves to the end. Does this sound normal? I can load all shells in my shotgun and all of them tight to end of casing and when I unload they are all over the place. Some casing ends aren't even flat, on a slight angle. Once the slug comes out it will not fly out the way it should? I have been finding that some shells are going all over the place. It doesn't seem normal to me that I can shake a sabot slug around like that. Some shells are purchased in Orlando, and the rest in two different places in Ontario. All different batch numbers. If anyone can help me with this it would be greatly appreciated. I couldn't find an email address for Hornady. Thanks
