I've played with the demo version a bit, and it's the old Powley Computer with updated powder tables, near as I can tell. You can get a freeware copy of Winload (Powley again) with badly outdated powder recommendations and no external ballistics. How badly outdated? Try a .35 Remington with a 200 gr. bullet. Winload suggests HiVel #2, discontinued in 1964. http://homepage.ntlworld.com/jmk/ for Winload.
My cardboard 1970 model Powley computer doesn't recommend HiVel #2 <!--emo&--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''><!--endemo-->
I have been using Load From a Disk for the past nine years, firts with an earlier DOS version and now with LFDW for Windows.
Before buying any of the load development programs I did as much research as I could, including phoning Blackwell (developer of LFD) and having a lengthy conversation with him. As I had been using a Powley COmputer with good success I was curious how LFD compared to it. Well, Blackwell said LFD uses the same mathmatics as Powley. LFD will give you all of the same parameters as thge Powley with one change. LFD groups powders into burning-rate categories and gives a list of all in that category. The Powley only read out in the IMR selection.
I have been greatly pleased with the results obtained from LFD and LFDW. Now since I have an Oehler 35 chronograph to check results I have been amazed by the close correspondence from the LFD predictions and actual chronograph data. The LFD gives much closer results, generally, than data in any of the major manuals.
In short, I wouldn't be without either! Your money will be well spent buying LFDW.
In regard to the comment on NECO's "QUICKLOAD". I have been using it almost as long as it has been available in the USA. While I cannot verify any data except velocity\fps, if the rest ( pressure, % of burn, etc.) are as accurate as velocity estimate the program is great. most loads are predicted at velocities that fall in the "extreme spread" range. occassionally it will be off 100 fps or so [ minority] but then it predicted the load for my 6.5\06 to 1 fps of actual velocity. I don't think it is any more expensive than most computer stuff & pays for itself in cost savings for load developement on powder, primers, gas to drive to shooting range, etc.
IMHO = #1 rating in value & usefullness.
I don't use computers to work up loads - I do it the old fashioned way - more fun, prolly safer too.
If you are interested in External and Terminal Ballistics results for your loads, there is a good free program at:
I'm responding to a very old post. Hate to hijack the tread, but a question. I purchased the windows version years ago, it came on a cd, I remember the label was rather "bland." I've looked everywhere and can't find the cd, nor any of my old computers have have had the product installed.
For what I used it for, mainly creating dope charts, ballistic tables, I was happy with it . I downloaded their free version but would rather have the old version back. Does anybody have a copy they could zip up, burn, etc?
As I understand after the author passed away, the family decided not to carry on with the business. What is on the site is a very limited demo. I read where one can purchase the produce, I tried, once it re-directs for a purchase, goes to a "404" error, page not there. Since the family wanted out of it, I'm surprised that it is offered for sale. Somebody needs to update the site and say it just isn't for sale anymore. The last update was in 2006. I purchased the product years ago, just can't find the CD. I will keep looking for a back-up copy, since it is no longer sold.
Thanks for responding.
There is a better interior ballistics program called QuickLOAD that is still updated and which covers a lot more territory and isn't limited to 85% to 100% case fill. If you don't care about the interior ballistics and just want to run tables, there are two exterior ballistics programs that come with QuickLOAD, one simple and one much more sophisticated, and lots of free ones at the JBM Ballistics site.
