I found some 7828 in the old IMR metal can for a decently good deal the other day, like $14/lb. It's my first time to use it and yeah, it is sucky to meter. I had to throw a grain short and trickle on the scale to get decently consistent results. That's a real PITA! Two questions arise from my first usage. In your experience:

1) How much better metering is 7828SSC? 4831SC is an improvement over standard H4831, but it bridged in my measure so badly I'm not sure if it's that much better overall.

2) It is truely interchangable (within lot2lot variation) with standard 7828 data as 4831SC is? I know this should be a slam dunk, but all 4831's should interchange too, and they don't!

IMR 7828 is my favorite powder for several carts. I bought some ssc to try in my .260ai & it works fine grain for grain vs 7828. I don't throw my rifle charges so I don't know about metering but it does fit nicely in compressed loads, less crunching for the same powder charge. I'm going to give it a try in my fav. .280 recipe & see how that works out. Should be good in my son's 06 w/ 180gr bullets too

I think the short cut 7828 may be just the ticket for fast 180-200 grain .30-06 loads at a reasonable pressure. You may now be able to load enough of it in the case to make 2900 fps or so, be interesting to find out. I bought some and am thinking of testing it with 160-175's in the 7x57, it just might work, but it's hard to tell.
