[QUOTE="TaergEno, post: 963527, member: 37489"] Oh, and I finally found some actual load data for the bullet I have. I found a Lyman book that was opened at Sportsmans Warehouse where I live and I browsed through it. I found the following: [B]210 gr. Jacketed Scirocco BC .507 SD .263[/B] [B]Powder | Min Load | Velocity (FPS) | Pressure (PSI) | Max Load | Velocity (FPS) | Pressure (PSI)[/B] RX19 | 83.0 | 2995 | 55,200 | 90.0 | 3167 | 62,000 [B]N560[/B] |[B] 88.0[/B] |[B] 3070[/B] | [B]57,200[/B] | 95.0 | 3217 | 62,500 H-4831SC | 83.0 | 2921 | 55,500 | 88.0 | 3072 | 62,100 AA-3100 | 83.0 | 2956 | 55,200 | 91.0 | 3108 | 61,500 IMR-7828 | 86.0 | 2956 | 54,200 | 93.0 | 3106 | 59,500 Magnum | 95.0 | 2981 | 57,900 | 100.0 | 3095 | 61,900 Correct me if I am wrong, but does slower burning powder increase the pressure that is created? Also, do you think that the above load data would work if using N160 instead of N560? According to the Vihtavuori Burn Rate Chart, N160 and N560 are close to the same burn rate? It appears that N560 is slightly slower burning than N160.
