Unfortunately that is the most dangerous way to do this!
The practice of slow powders in reduced loads is specifically not recommended because it has been known to blow up guns and people. It is called the Secondary Explosion Effect (SEE).
If you look at any reloading manual, they always give a must minimum load for each powder. The SEE is the reason why.
Just picking a powder an reducing it, particularily a slow powder is a recipe for disaster.
That is also why I recommended you talk to the experts who have worked out safe reduced loads and will give you accurate and safe information. I have done this numerous times for different caliblers and would only use a load that comes from guys who know what works and not.
