[QUOTE="Fitch, post: 369713, member: 19372"] They are as real as any other prediction of how a load will function in your rifle. Load manuals with loads developed in different chambers, different brass, different barrel lengths show what was done in some rifle or test barrel which may or may not have a reasonable relationship to yours. I frequently see bigger variations between load manual MV perdictions and what I get than I see between QuickLoad and what I get. I use QuickLoad a lot. I don't think I've loaded any ammo that wasn't modeled first in QuickLoad for at least 3 years. It isn't my only data source, but it is a major help both in picking cartridges and in sorting out how much of what powders might work well in a cartridge. I compare the results with load manuals when I can. I also chronograph the starting loads at the range and compare the MV numbers I'm getting with QL predicitons to make sure nothing is going off the reservation. QuickLoad is a good tool to have at your disposal. It is better if you have it to use in person. That allows for fine tuning it with the actual fired (in your gun) case water grain capacity (of your brass), seaing length for the cartridge matched to your chamber, etc. Each of these tweaks improves the model. I use it in combination with the bullet makers load manual and powder company manuals to pick a powder. zero in on a charge range, start 10% below max and work up toward the max checking the measured MV against the predicted MV. It's a tool, one of several, nothing more, but it is a uniquely useful tool because it allows what-if exploration of multiple options before spending any money on powder or primers. . It is especially useful when there is no bullet company load data to start with. Powder company manuals with don't have "your" bullet listed are relatively useless. Different bullets seated at different depths can make a big difference in pressure. Fitch [/QUOTE]
