Slide rule device that determines powder type and weight? Name please.

**rayraywolf** · 08-31-2018, 10:56 PM

I have heard of a slide rule type device that gives the operator the correct powder and weight for a given case capacity and bullet diameter. I heard about this device years ago and now I can not remember what it is called. Anyone else heard of this?

Powley Computer for Handloaders.

Anyone ever use the Powley Computer for Handloaders?

**RichardB** · 09-01-2018, 12:17 AM

yes I have. Especially valuable for wilcats

Powder selection is limited, but results are reliable.
i I knew Homer when he worked at FA and he was a competent engineer.
In the days before the IBM luggable PC when we ran everthing in Fortran or Colbal his programs were as good as it got.

Does it come with a pocket protector?

LOL Hogtamer

Not to detract from the post, but wondering if the "young 'uns" would know what a slide rule is? And while speaking of "post" . . . IIRC, my first slide rule was a "Post" brand.

The Powley Computer works very well, though I haven't used mine in years. It came in handy for me in developing jacketed bullet loads for a .375 Whelen Improved.

I learned to use a slide rule in High School (and still use that knowledge to adjust a Lee scale!), but when I tried a Powley Computer, I remember getting lost. Or perhaps I just didn't have enough info to feed the computer...

Speer also had a similar device out for awhile.

After Outpost75 told me the name Powley Computer for Handloaders, I googled it. It appears someone set up a free website that a person can enter their parameters and it will give outputs of powder type and weight.

jem102, I did not know Speer had anything similar. Do you know the name of Speer's?
