[QUOTE="Lefty7mmstw, post: 2528524, member: 48043"] The fastest I've pushed a 180 from a 24" bbl'd 300win is the 180 hdy sp with old mil-surp h4831 and that was 3150 fps. I decided to go with a 165 hdy at 3250 fps or so with rl22 and run 180 and heavier through my 300rum rifles where I can easily hit 3300 fps with a 180 or 3,000 fps with a 225. From the Hodgdon data online it seems as though you may be able to use Magnum to get in the 3150-3200 fps window with a 175-180 using Magnum, but as a ball type powder it will not be 100% temp stable, but neither are the rl powders I like to use. As long as it stays accurate you may be able to use it. I've played with Magnum back when they called it "Big Boy" but I never quite got a load I liked enough to buy more of the powder. As far as 7828 being temp. stable, not really, but it usually ssays accurate as long as you are putting enough bullet weight on it for the cartridge. I've had trouble with 7828 in a 7rem using 140's; hot weather it was accurate in one rifle, but the load went to pot in cold weather and I used either rl22 or 4064 after I found that issue. Another 7rem was fine in all temp's with 7828 and a 140. The 7rem in question also was stable in all temps with 7828 when I upped the bullet weight to 150 or more. [/QUOTE]
