Clark, if you have access to a Speer #8, I'd love to pick your brain. I've heard it's the last of the really intrepid recipe books. If you'd SELL a number 8, I'd be delighted.

From what I have read about it, in the earlier years, Speer worked up data for some guns without really doing pressure measurements and just left it up to the Ballistician to make a judgement call on the load's quality, safety, etc.(Three load ranges) Other's were not re-evaluated for many years.

Now Speer is changing over to Piezo-electric pressure testing and is phasing out the copper-crusher methods gradually. This has lead to the later editions with some toned down loads. The 357 Mag is one noteworthy one.

I try to match the approximate time I purchased my smokeless powder to the approximate edition of the reloading manual publication dates.

This is a reasonably half assed way of matching a powder lot year to the load data time frame.

Follow normal safety considerations also.

Have Fun

Didn't we all just do this thing a few weeks ago?

Well just my .02 worth, but I used to use Elmer keith's pet load for the .44 magnum. I've had to reduce that load by 2.0 grains. Pressures with Alliant's version of #2400 seems to be faster burning, that when Hercules made it. My pet load for "N" frame Smith's in .357 magnum had to be reduced by 1.5 grains of Alliant's version of #2400.
I do agree that better pressure testing systems may be part of the reduction in powder charges, but I also agree that the lawyers have done some of the screwing up of load data as well.
Another powder that seems to be faster burning is IMR-4895. I had a sweet load for 150 gr. Sierra's with that powder, and now IMR's version is faster burning than Du Pont's was. (At least in my rifles.)
All I can say now is, "Ya'll be careful now."

Hutch, try checking E-bay. Go to sports, then hunting, and do a search on Speer (or Hornady or whatever). I lost my Speer #7 (and my Hornady II)in Hurricane Andrew and was devastated, knowing that I could never replace them....WRONG! Not only did I replace them but I also got some other older books too! You may have to wait a week or so for what you are looking for to show up but I promise it will show up.
