Daryl, most likely she meant 1140gr as the ammo is typically 570gr projectile and especially so in factory Hornady 500 NE 3"

FWIW the Hornady factory ammo clocked 2080fps in my old 500-3 1/4" NE 26" barrels when I tried a couple. So maybe a little faster in a 3" chamber.

Gave her a great shove eh

Did well hanging onto it.
