I luckily put in a big order at Grafs 2 months ago - they still had plenty of imr4064 then. Cabela's gets stuff in store once a week. got 6 lbs of win.748 last week, and a bunch of hs-6 the week before. there is never more than one type on the shelf at a time though.
I haven't started rationing my milsurp shooting yet, but fear it may come to that. right now its far to easy to belly up to the indoor 100yd line several nights a week and forget about what's going on outside. We have a very great range worth giving a shout out - Elite Shooting Sports https://www.eliteshootingsports.com
