Is anyone using StaBall 6.5 behind a 25gr. 17 Rem. bullet? If so, how well is it doing for accuracy and velocity. My favorite for the 25gr. bullet has always been IMR4320, but that one is no longer made. IMR8208 has been just as good, but try and find any. The new StaBill 6.5 looks like it would be pretty darn good, but before I buy 8lbs. of it I would like to get some feed back.
