IMR 7828SSC in 243 or 260?

[Charlie Papa]

I picked up some 7828SSC awhile back since it has a burn rate between H4350 and H1000 and thought it might be good in 243. And also because it was the only thing available. Unfortunately, I don't know anything else about it.

Is it very temp sensitive? Does anyone have a good load for it in 243 or maybe 260?

Thanks!

Ive used it for the past 2 years in my 260's, not temperature sensitve and doesnt hit pressure fast. 46.2gr/139 Scenar gets me 2850-2900 fps in 24/26 in barrels
this will be a compressed load. A little dirty, but who cares? And,,,you can find it.
