45.0 Gr of Varget, Nosler 120 Gr BT, CCI 200 primer. The .284 120 Gr BT has a heavy jacket designed for knocking down steel targets, and are supposed to work well on game. That load is giving my son'e rifle <1" @ 100 yards.
A load in which he has killed a couple of deer with is a 120 Gr TSX with 46.0 Gr of IMR 4350, CCI 200 primer. He is shooting a Browning Micro-Medallion with a 20" barrel. He started to shoot the TSX load when he was 9, and he just turned 11.
The 7-08 is a great caliber to start with..............and end with.
