PRE Hi-Skor 700 or 800 load data

[chas442]

I have some old Hi-skor. It is not 700 nor 800. It actually looks like miniature Trail Boss.
I have very limited data. Does anyone have some really old load books that might have load data?
any help would be greatly appreciated

IMR introduced “Hi-Skor 700X” for target shotshell reloading in 1963.

Man, that has to be some old powder - I still have a can from around the late 70s, and it is labeled as Hi-Skor 700x.

For what it is worth, that scanned page of load data posted above is the right color, font and format for an original IMR or Dupont Handloader's Guide. BUT, I compared it with the 1983 Dupont guide data for 700-X, and the data in that scanned page is NOT the same as the 1983 data. It is close for most loads, but not the same.

I know that proves nothing at all - "Hi-Skor" powder could be different than "Hi-Skor 700-X", or the data could simply have been revised. But just based on that difference, if you are going to try to use it, I would certainly NOT use modern 700-X data. Stick with old period data. And do realize that the appearance of the powder means little - 700-X has been revised at LEAST 3 times, and probably more, since the 70s.

My oldest book speer # 8 (1970) shows 700x for 380, 9mm,38..... but no Hi Skor in da book....

The following data is said to be from speer # 7, Go to http://forums.handloads.com/forum_posts.asp?TID=6211

Does the powder still smell good? If not toss it in the garden.....

Hi Skor came in a Black and white can with DuPont in red letters.
The starting load was 2.3 gr Hi-Skor. up to 2.8 gr, 148 gr .358" Speer HBWC, 833 fps, Rem .38 Special brass, CCI 500

The only other loads for it in Speer #7 are .45 ACP, 3.5 gr - 4.5 gr, 200 gr LSWC, CCI 300, 639 fps - 881 fps in GI brass and .45 AR, 3.0 gr - 4.0 gr, 200 gr LSWC, CCI 300, 688 fps - 815 fps, Win solid head Auto Rim cases.

I have never loaded DuPont Hi Skor, and can't confirm these loads....... THIS IS THE INTERNET

USE CAUTION AND WORK UP YOUR LOADS

I recently read an old manual that said the old Hi-Skor was not the same as the 700-X. Now if I could remember which old manual.

Thanks for all the info guys. I have the same page that TCOOK put up. I have loaded 9mm with 3.5 gr under a 115 gr coated bullet and a reduced power recoil spring. It's a fun mild target load. I've also used the lower end 45 ACP loads and they work well. The reason I'm looking for more data is I was given a 10# can by a gun shop owner that couldn't sell it nor could he use it as he could not find load data.

I have some old books from the 40's-50's I will look for them tomorrow. What calibers might you be looking for data for.

IIRC the old Lyman and Ideal books had the data you were looking for.

Hi-Skor has always been with the 700x and 800x powders from when they were stand alone shotgun powders. There were others but only 700x and 800x survive. Sometimes when writing the powder names they leave off the Hi-Skor part but the powders have been the same since they were released.

They were claiming High Scores (Hi-Skor) with their powders.

 

[chas442]

Taking into consideration the time frame that Hi-skor was discontinued, I would like data for 155 gr bullets in 45 caliber. I shoot a bit of bullseye competition. I have a colt that is tuned down to barely cycle 3.4 grain of bullseye powder under selfcast 155 gr bullets. I've pretty good accuracy from the Bullseye powder. I noticed in the load data that there are a number of small powder charges listed. That would lead me to believe consistant ignition on small powder charges

DuPont Hi Skor was a distinct powder formulation and granulation.
It was replaced by Hi Skor 700X which is NOT the same stuff.

The page tcook shows in post #3 is about all you are going to find. Hi Skor was a shotshell powder and there was less overlap in those days. P5066 was the culmination of the No. 5 and No 6 development and was a very good pistol powder. IMR has not made a dedicated pistol powder since they dropped P5066.

I wish you luck in metering it!

I have almost a full pound of very recent vintage.
Tried it in 3 different powder measures, a Dillon, a Lee Pro Auto Disc & a Uniflow from RCBS.
All I can say is ICK!
(yes, even the great & powerful Oz... I mean Dillon, has it's draw backs)

If any one is local to me, I'd gladly give it away.
Just PM me & it's yours. (will NOT ship)

I read the OP I correctly. I thought the question was about Hi-Shok 700x and 700x of which there is no difference. I didn't realize what was actually being asked, sorry about that!

What if? There was only the first one produced, no others. Could it then have been just called " Hi-Skor " for short.

 

[243winxb]

My 1959 Shooters Bible list all Dupont powders, so the top of the page said. PB shotgun powder replaced M X . There is no "HI-Skor" listed.

 

[chas442]

That's interesting. It appears Hi-Skor was produced before 1959. Stuff still works pretty well.

 

[243winxb]

Before 1959 shotgun powder was " M X" from the photo. M X was replaced by PB .

 

[chas442]

Pretty cool. Am I safe to assume that it is powder from 1944? I'll post a photo of my Ginormas can of Hi-skor next time I am the area of the powder location

No, do not assume anything.

I assume that "Hi Skor" and "Hi Skor 700X" are the same powders. When it was first produced in 1963, there was only 1. There was no 800X. When 800X was born, then there were 2. So the 700X was added.
