pdf version of book can be found hereRight. I wish I still had my copy of that old book. They didn't care if a powder was ideal, they showed what could safely be done with everything they made.
Agreed. I keep it around for .17 and .22 K-Hornet loads. It's just about perfect for those rounds...IMR4227 is pretty fast for a 223. Notice you're getting high pressures without high velocity. I use it for 32-20, 218 Bee, 22 Hornet, 357 Mag and 44 Mag. You can use anything you want, but I would find a different powder for a 223.
No idea, but I have the pdf copy. Happy to post it if you advise me how. 2.58MBJoh,
Be cautious with old data. The basic manufacturing process for IMR powders was revised a decade ago, and, additionally, the primers made today are differently formulated than they were when that manual was published. Brass has changed some, too, so it is hard to say exactly how close the performance you'll get with today's components will be. Start low and work up carefully. In general, avoid getting below 60% case fill (70% is better).
