i purchased a box of hornady .45 sabots with 38-180g xtp's.these were old stock at a local gun shop.i want to try them in the .45 super-disc.the bullets don't seem to fit to well,when you push the bullet to the bottom of the sabot the petals flare out quite a bit.do you folks think this is normal or could the sabots have shrunk due to out-gassing.thoughts?......karl
