[QUOTE="AJ Peacock, post: 249772, member: 4885"] The H-1000 load I used was 89gr (106% load density) for a 66.8k PSI and the following velocities 20" 2553fps 23" 2640fps 26" 2712fps 96gr Retumbo gives the following 20" 2660fps 23" 2747fps 26" 2819fps But it shows 96gr retumbo is 113% load density, so you may not be able to get that much in there. It also shows an above recommended pressure of 73k psi 90gr Retumbo gives a 105% load density and the following velocities 20" 2546fps 23" 2577fps 26" 2652fps with a moderate pressure of 57.5K psi Hope this helps.
