Re: 6.5 stw
There is some light bullet loading data on accurate reloading dot com. Layne Simpson did an article in Shooting Times in September 1999. There is data on the net, try google seach.
I had a chubbie for this cartridge for a while about 10 years ago but never got around to building one. With the very short barrel life, I don't see myself building one. Now, it's leaning towards the 6.5-284.
