Keep in mind this load was developed for a semi-custom rifle
built on a Savage PTA with a Broughton 5c barrel that was throated for the 175 gr Matchking.
After working from 40.0 to 49.0 grs without pressure signs of any kind I settled at 46.6 grs over a Fed 210 primer. This load is ultra accurate and kept me in line with the top listed velocities in the 3 reloading manuals that I use most. This is over Alliants listed max for the 160 class bullet so start way below this level.
