Due to shortages of IMR brand powders..I took a flyer & ordered 8 lbs of Accurate or Alliant brand 4064 powder..I was thinking what the hey it's available..3 months later I get a nice e-mail from midway explaining the B/O situation ...If & when that stuff ever gets here...What can I expect when using that powder in my 243 win with Berger 88 grain flat base hollow point match bullets? ...Thanks in advance, mike in Ct
