Re: 708 urgent help
I used your specs . 2.800 COAL , 55 gr H2O case capacity ( fired case ) , 23 inch bbl , 140 accubond , the 7-08 is rated to 60191 PMAX pressure .
RL17 - 45.5 gr , 60102 pmax , 2913FPS , 100.6% case fill MAX LOAD
45.6 gr , 60544 pmax , 2920FPS OVER MAX
H4350 -46.7 gr , 59961 pmax , 2911fps ,108.9% case fill MAX LOAD
46.8 gr , 60455 pmax , 2917FPS , OVER MAX
H414 - 46.2 gr , 59956pmax , 2881fps , 100.6% case fill MAX LOAD
46.3 gr , 60401 pmax , 2887 fps , OVER MAX
varget - 42.3 gr , 60125pmax , 2826fps , 101.4% case fill MAX LOAD
42.4 gr , 60560 pmax , 2832 fps , OVER MAX
I think I covered all the powders that were mentioned . if you want to see a different powder let me know . general rule of thumb is to start 4.0 grains below max and work up while watching for pressure . hope this helps . Jim
