Ramshot True Blue has low muzzle flash, fireballs do not come out of the barrel. This is favorable to most.
This powder yields above average accuracy in our vast tests. One reason is it is very easy to quickly load consistent charge weights without checking each one, due to its ease of metering.
There is a large amount of load data for this powder. Ramshot even lists +P loads for it. There is hardly any data available for less than 115 grain bullets, and that is the weakness. We took guesses and worked up for loads below 115 grain bullets to learn about it. This is pretty easy since the load data for True Blue and Silhouette are very similar. True Blue generally uses slightly more powder to get same result as Silhouette.
We find that True Blue is not an "easy" powder to attain in periods of shortages. We looked weekly, and could not even find 1 lb of it, for literally years. True Blue is probably the most underrated, underused powder in the world of 9 MM. It does it all, it has almost no real weakness, and its in the spectrum of medium to low cost choices.
To us? Ramshot True Blue is simply, easily, one of the best powders for 9MM you can buy in the known Universe. It can do plinking, it can do accuracy, it can do low charge weight plate shooting, it can do 9 MM Major.
