jjohnson, at first when I saw the size of powder flakes, I had my doubts - "How will those big flakes going to meter in my squeaky tight Pro Auto Disk wipers???" I don't have the same doubt now. Even with the 0.2-0.3 gr variance on range test #1, the shot group accuracy was very acceptable for plinking/range shooting. Using the older (looser tolerance) Pro Auto Disk and smaller 0.1-0.2 gr variance for range test #2 and #3, the shot group accuracy improved for even match shooting practice. I may hand weigh some charges for bench rest shooting for range test #4. For me, the biggest benefit from Promo is the fact that I can come fairly close to many of my factory JHP felt recoil for real world tactical practice (we fight like we train). I do agree on the packaging. If they sold Promo in 4 lb containers, they would probably sell a lot more (but they may sell less of Bullseye/Red Dot). For the price, I say add Promo to your next HazMat order and have fun.
