Thanks for reaching out Allen! Barnes' XPB projectile is 100% lead-free. It's made of solid copper. The Utahan company does in fact load some bullets that contain lead (such as the Buster brand bullet), but they only put their VOR-TX label on cartridges that have lead-free solid copper bullets.----Allen, The DE owners manual says not to use lead bullets. This is a full lead projectile with no jacketing. A TMJ bullet where the lead core is covered by a copper alloy jacket is fine to use in your DE pistols.
