Help with a start/stop load for RL 17/HV100

[sewwhat89]

If anyone could run some numbers to help me get some starting loads for RL17 and HV100 I would appreciate it. I don't know what information you need to do that, but here is some anyway.

300 RSAUM
26" barrel
208gr AMAX
3.005" COAL
RP 9.5M primer
300' elevation
50F temp

Cartridge : .300 Rem SA Ultra Mag
Bullet : .308, 208, Hornady A-MAX 30712
Useable Case Capaci: 68.011 grain H2O = 4.416 cm³
Cartridge O.A.L. L6: 3.005 inch = 76.33 mm
Barrel Length : 26.0 inch = 660.4 mm
Powder : Alliant Reloder-17

Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.

gbp - I think he was referring to Hybrid 100V from Hodgdon and not H-1000.

That looks great for the RL 17. I went ahead and loaded from 58 to 61 grs to get an idea.
