I switched to the black Crushed Rib Sabots for the 250 and 300gr Barnes Expanders I shoot. The suppiled sabots where a little tough to get down. The Crushed Ribs are easier but still has some resistance which is what you want. I also buy extra Crushed Rib Sabots for the 250 and 300gr XTP's I buy in bulk. They work great for the XTP's too.
