What powder are you using to get that speed?? nicegun)
That's pretty fast. What is your overall length? I have been curious anout RE26. I am a little concerned about temp sensitivity though. Have had it with RE17 enough that I went back to the Hodgdon powders.
I load them in a Ruger and fit to mag length, they are at 3.335" to fit/feed reliably. They are accurate, but only at 2907 fps with H1000.
