Loads I run in my 284Win R77 with 19" Shaw barrel with .0005" taper bore.
120gr BT 52.5gr R15 at 3200 fps
139gr SP 55.5gr IMR 4350 at 2900 fps
140gr SB 55gr R17 at 2900 fps
150gr NP 47.5gr R15 at 2900 fps
160gr NP 55gr R17 at 2875 fps
These are all hunting loads and quite effective on game.
These loads developed watching speed, pressure signs and accuracy.
Used Win brass and Win LR primers.

I've run the combos showing the loads using RL-15 and settled on the 120 NBT for Deer.
