Yea - a "bit" confusing. Now that it's "clear", here's what I've done with Red Dot in the 303 Brit. All the bullets are heavier than 123 gr, so the loads would all be safe with the 123 gr bullets. I'd work in the 4.0-15.0 gr range with that bullet with the same cautions I gave before.
OAL 3.075" 2.725" 3.175" 174gr RN 178gr Cast 247gr Cast 6.0 grs 625 fps 10.0 grs 950 fps 11.0 grs 1100 fps 12.0 grs 1225 fps 13.0 grs 1350 fps 1600 fps
What I found interesting were the large increases in MV with each additional grain of powder, and the difference in MV between the Hornady 174 gr RN Jacketed and the slightly heavier 178 gr cast bullet.
What load gave you the best accuracy?
