Normally I shoot Rd ball. But occasionally I do sabot for a change up. Here's a Link to a business I've purchased from in the past many times. Pretty interesting reading if you have the time to bump around in their site. Good products, nice folks, great prices.
www.prbullet.com/pts.htm Check it out. Only sabot and bullet combo I buy period. Once you try these Dead Center Bullet sabot's. Like me you won't consider anything else there after.
