I'm using 2 triple 7 pellets, and I was shooting a cci I think? 209 primer, but yesterday I was shooting winchester triple 7 primers, and it was burning a hole clear through the bottom part, or the cupped shape part of it. Thats what I have always shot, and those bullets were accuarte as can be, but the 2 boxes I bought this year shoot like crap, and the sabots look like this. Does anyone have a picture of there sabot after being shot? Thanks
