I've noticed in my 8th edition Hornady book they list the powders in different orders at different times. I'm trying to draw a conclusion as to why they do this. I've read the book extensively and can not find an answer. For example in the two tables below one list 4064 first and the other Varget. One is for 154g and the other is for 162. One might assume most accurate powder tested is listed first but I do not know that to be true. Any input is appreciateD.

Don't they list them in order of velocity of max loads? Could be a different manual I am thinking of though

They may but they generically round them all off in 100' sections. So that is not clear to me either.





Actually since some of the faster and slower powders are on down that page im going to say no.

I've noticed manuals scramble the powders and there seems to be no rhym or reason for doing so. Even seen a powder listed for a cartridge and bullet, the next page on a heavier bullet certain powders are gone. So off to Hodgdon.com I go.

Sometimes it irks me that in my nosler manual they will have a load for the powder im using listed for a 140 grain bullet and a 160 grain of the same cal, but they don't show that powder for the 150's.

^^Exactly^^

That's why I reference my two 5 year old manuals AND consult Hodgdon.com

I cross reference everything I can and try to use data on similar design bullets if possible.

I would think this is because some powders are not suited for some bullet weights. The greatest example I can think of is H110 is for heavy for caliber loads and does not perform well otherwise. You will seldom even find it in standard weight bullets and never in lite ones.

Edit: I'm a dummy. Didn't see you was listing a heavy and lite without data in the middle. That is strange.

Right... but why would IMR 4350 be good for 140 grain nosler partitions and 160 grain nosler partitions but not 150 grains? All in same caliber of course.

I know a few do that because they didn't find acceptable accuracy when testing so they omit it from the powder list.

It was the Lee manual I was thinking of that orders the load by slowest to fastest max velocity.

Look at the starting load weights. For each cartridge and bullet weight the powders and its loads are listed in order of the lowest charge weight that resulted in the minimum pressure designated for that combination.

I had another question for Hornady so ask this question while on the phone.

This is a perfect example of why every handloader should keep a veritable library of reloading manuals, both new and old. I have Lyman and Speer manuals going back to the mid-1960s, as well as current offerings. This way, I can average out the loads from several different sources and get a rough idea of the powder weights I will try. Perhaps the most useful info is the top velocity a load should achieve; then using my chronograph, I know that when I am approaching the top velocity, I am also getting close to the max load for my rifle.

In the OP's first photo, note that Hornady lists loads for both W760 and H414. These two powders are the SAME, made in the same factory, and the different recommended loads can only be explained by the techs using different production lots of powder. And if your manual lists loads for your favorite powder for 140 and 160 grain bullets, but not 150 gr, there's a good bet that another manual will have your load, or you can just extrapolate between the loads for the 140 and 160 grs. And again, your chronograph will usually tell you when you're getting warm by the velocity you're getting from your load.

And regarding the haphazard listing of the various powders, perhaps that is due to the sequence in which the powders were tested. There's certainly no other rhyme or reason.
