I've been playing with Quick Load and began using powders that are not 'normal' for various loads.
For example, for a 223 remmington I chose Alliant 2400 with a 15.0 grain load to give me the same pressure Varget would with a 24.6 grain load, about 47k psi. 15.0 will give me a mv of 2900 fps pushing a 55 grain VMax.
I understand burn rates. Varget is about 172 and 2400 is about 101. I have seen loads using Clays for the 223 which has a burn rate about 11, but the mv is only around 1000 fps.
Is this dangerous? Should I work up the load that I normally would and look for pressure signs starting at 10% below my target? Is this really as simple as it looks or am I missing something? I look at the graphs and understand the numbers Quick Load is calculating and don't see anything wrong.
Thanks,
