Shooters that shoot 7828 or 7828ssc powder what have you seen or noticed with temp changes? Is it a bad powder to use? I have a good start on a load with my 280AI but if its bad I don't want to use it

IMR 7828 is an excellent powder. I have used both versions and use it exclusively in my 270Wby.
 
It's been very good for me as well. 7828SSC has worked very well in a number of my rifles. Awesome in the 300 Weatherby and 7mm Mashburn.
 
The title of this thread puts a smile on my face each time I see it. I'm so tempted to write, "Well, you do have to be careful not to speak too harshly when it is nearby"; but, then, people would think that I was being cheeky. Ergo, I'll maintain my gleeful silence.
 
I've tested it, one of the most consistent powders for temp swings.

280 AI
59.0 IMR 7828
F210M
Rem. Brass @ 3.2800"
75 degrees HI-2807 LO-2779 Avg. 2798 ES-28 SD-11
18 degrees HI-2812 LO-2774 Avg. 2795 ES-37.39 SD-14.17 (Ammo was brought to temp 2 hours prior)

Pretty consistent if you ask me, but this was back on 10/21/2003, and 11/22/2003 Powder Lot # E02MA28 L8231

I forgot to mention I was using a 175 Nosler Partition.
 
I know it's probably used more in higher capacity cases, but that was my favorite powder in the 260 Rem I use to own. Very accurate and never had any issues whatsoever with it.
