I am just wondering if the popular choices for powder are based on availablility or tried and true testing...Not trying to ruffle feathers just wondering...(I have been using H4198 for my .221 but do not see many others that use this, some say hard to meter...never had a problem)...just wondering. I might add that I kilt an apple at 246yds today with my load...poor apple did not stand a chance, head shot...for skeptics...it was ethical...the apple was froze..... :lol:
