My son has used one in Ga when he was stationed there. The load was a 300gr Hornady TXP @ 1700FPS from a 20" barrel. He said the last one he shot running just cartwheeled. Over a foot of penetration and a 2" exit. The reports Ive heard from those using cast bullets claim whitetails will walk ten or 20 yds and collapse. If you want to do all the "knock down" calculations, the 45 will well outclass the 30-30 and other accepted deer cartridges.
