Hey now! Don't you know imr7828 is an outdated and useless powder!?!?
Temp sensitive, single base, made by IMR???? You don't need that boring old nonsense, don't you know that unless your running h1000, retumbo, or rl26 in a magnum you might as well just shoot a .308, and at that point you're basically just as well to throw rocks and save your money, same trajectory! send that archaic old powder to me, I'll take it off your hands free of charge, waiving my usual "disposal fee"
I love the stuff, and accurate shooter did load
Work up with the 195 tipped matchking, which is about as similar to the 195 eld m as it's possible to be, including 7828 powder.
Your charge weight sounds appropriate and roughly in keeping with their findings here, as is the velocity. Image of freely published data provided free of charge!!!

I really have felt smug these last years watching people almost willing to sell their soul or fight to the death out of desperation for h1000, retumbo, rl26, and maybe n570 (though apparently barrel life with that one is about a dozen rounds, barrels get pricey at that pace of erosion
). Meanwhile I've been shooting 7828 and can't complain about a thing. Find it on auction from time to time too, still paying too much BUT it never goes for anything close to what h1000,retumbo,rl26, or rl-anything goes for.
Nobody seems to get too excited over 7828 anymore. It is the original magnum powder as far as I'm concerned, still the one against which I judge other slow burners, one of the best!
