Dupont 700x the same as Hodgdon 700x?
 

I have two unopened cans of Dupont 700x is it a direct replacement with Hodgdon 700x? Thanks

You have DuPont before they were called IMR and of course before Hodgdon absorbed them ? I’ve got very little experience with 700 or 800 X , but with what you have I’d look at an older IMR manual or possibly a manual from DuPont which would be older yet and see what charge weights they had against what Hodgdon says for the 700X of today . I’d be willing to bet it won’t be more than a grain or two difference .

"Hi-Skor" 700-X was the great powder when I started skeet shooting in 1971 - 3 when I was stationed in San Diego. Used it in 12-, 20- and 28-gauge. Got to Alaska in January 1974 and others at the Chugach Rod & Gun Club were appalled and the newer DuPont guides didn't have the 20- and 28-gauge loads I'd been using out of a 1967 guide. In the 1975-6 DuPont guide the 12-gauge AA 1 1/8 ounce load with Winchester primer and wad was 19-grains of "Hi-Skor" 700-X. Same in the 10/90 IMR guide.

I would like to use my dupont 700x in pistol loads 38 special 158gr and 9mm 115gr lead, does anyone have access to an old data sheet? Thanks Craig

Here you go Craig. See attached PDF.

In a .357 case, 4.4 grains of 700X; 158 grain lead bullet is very accurate. Six shot group @ 50 feet with a S&W M28 six inch.

I called Hodgdon technical support and yes dupont 700x is a direct replacement for imr and Hodgson 700x. Craig
