I use an old RCBS program, about 10 years old or more, called PC Bullet. The programmers went out of business and RCBS quit selling it. I don't know with what they replaced it but I believe they have a similar one. I like this program as it has all I require and it has served me well. It incorporates load information from several sources and has exterior ballistics included in addition to which you can download chronograph data. Check RCBS, they may have a replacement. I also know that AccuLoad has facilities for load information but since I have much old data I retain I've not considered either using it or trying to transfer my data from an old Windows 95 computer.
