Thread: 280AI data?

What is the end objective Danny? Long case life, highest MV within some specified limits ? I think you will find that 2213sc will be 100 ft/sec off the quickest loads for a given peak pressure, but I've found it to be temperature stable when the double-based powders are perhaps not so much. Capable of low ES and the best accuracy of powders tried in my 280. If it is doing what you want at around the 62gr mark behind the 140s I'd stick with it.
