Promo load shot / lead has a lower percentage of antimony (1-2%). Higher quality /more expensive game and target loads have 5-6% antimony resulting in better patterns, penetration and less shot deformation.

Promo loads are fine for everyday shooting at the range. But in the field, I want the best shell performance I can get to minimize injured or lost birds. It is worth the extra cost to me.

That said, I agree with Jagermeister, not sure where lead is going? I believe non-tox is the future.
