I have access to both pretty well. Locally the XTP Mags are cheaper. But I'm finding that online I can find everything cheaper yet and online the Deep Curl is cheaper. So i'm just going to start buying bullets/sabots online. I have a equal amount of XTP Mags and Deep Curl now. So the big factor is what will happen out in the field with Deep Curl. If they drop the deer quicker then the XTPS thats my bullet then.
