Another question I have regarding the 7828 is whether most of you are using standard primers or magnum? As mentioned above, I shot the best groups ever out of my .270 WSM the other night. I had a 3 shot group of 0.6" and the 5 shot group with that powder weight was 0.9". So last night I decided to load up some more of that recipe, using a smaller powder weight change to confirm the sweet spot. I was double checking to make sure I was using the same cases and seating depths as before when I noticed I had written down that I had used CCI Large Rifle primers. I had that written down both in my logbook and on the label on the box. I couldn't believe I would have used standard primers for such a slow powder, but there it was. I had loaded those rounds 6 weeks ago and didn't shoot them until now. The only thing I can think of is that one of my manuals, the Speer lists that powder and bullet wt and they don't indicate a magnum primer.
By the way, I did solve my powder measure metering problems with this powder last night. As mentioned, when I used it before it was with my Lyman 55 measure and had an awful time with it bridging in the drop tube. Then I remembered playing around with my old retired Lee Perfect Powder Measure awhile back with the really long stick powders. I hadn't thrown any charges to measure them, I didn't even have it mounted to the table anymore. I just remembered that at least the sticks didn't bridge during the drop. I remounted the old Lee and dialed it in, hoping just to get within a couple grains of my target weight and then trickle it in. Hmmm... the dang thing not only didn't bridge, but it threw consistent weights to within 0.1 or 0.2 gr for 20 straight drops. Half the throws didn't even make me trickle any powder at all to get right on the money.
I can't remember now why I retired the old Lee Perfect Powder measure. I guess because the Lyman was considered a classier piece of equipment. Now they are both mounted on the table side by side.
