Speer data online

Figures since I just bought the manual...............................
 
About darn time. I was starting to think they were a bunch of Luddites.

The online handgun version has load data for exactly one cartridge. If you load for the most popular handgun cartridge in the world, you're in luck. Anything other than the .460 S&W Magnum, not so much.

I was able to scroll down just a tad and find data for a whole bunch of handgun chamberings.
 
Thanks Toprudder! Speer seems to have a bias against Hodgdon powders (or at least the ones I use!). This load data is more specific than I'm used to- COAL: fine, min/max of course; primer? Eh, ok. But then they throw in what case to use... on a per-powder basis? That where it starts making less sense- to me those are fine-tuning tips. I can't imagine anyone running out and buying s bullet, h powder, x brass, y primer and then have to try out an OCW. To me, all these details are what I finally did after finding the perfect load (with a single weight of powder).

Absolutely, Kudos to Toprudder.

I agree, but I am one that appreciates as much data as they want to give me so that I can dump it in the decision hopper. Some I ignore; some I consider, because I am going consult at least two other sources when developing a new load. I usually have questions that are not answered in all reloading manuals. In this case I, like you, find it odd that they would go into minutia of case used, but not disclose barrel length and twist rate, which is right there with powder charge in determining muzzle velocity.

It makes me wonder how much of the reloading data published by different sources is actually based on testing done by the source company and how much is interpolated from other published sources or mathematical models. Don't get me wrong, I am Ok with the models, engineers use them all of the time, but what I do question is the margin for safety that corporate attorneys have them build in to the results.

I find the absence of this data disappointing, but not all that uncommon. If I could get barrel length & twist data from all of the manuals I consult, I would spend a lot less time with my chronograph.

These data are fairly specific and detailed as they should be. Even if you bought all the exact same components and assembled the rounds to exactly the same dimensions, you might not get exactly the same results because you are not firing those rounds out of the same firearm/test barrel/whatever. Those data are not absolutes that
are set in stone guaranteeing uniform performance in all firearms but rather suggestions based on a specific set of tests that you are unable to duplicate exactly. You must work up loads with your components, conditions, and firearm using the data as a guide to where to start and as a warning about going too far.
 
Speer and Alliant are connected, and I believe Alliant actually produces the data for Speer. If you look at any of the Speer data using Alliant powder, and compare it to the data on the Alliant website, you will see they are identical charge weights and velocities.

I found website information through a private message to the Alliant rep that is on another forum, asking if they were going to work on data for a specific caliber and powder (460 S&W and BE86 powder) and he informed me they had just produced this data and gave me the link to it. He also mentioned that Speer is going to have a new manual out soon.
