[QUOTE="65WSM, post: 1949792, member: 9551"] The performance of "Swiss" Nitrochemie powders is amazing. That is why General Dynamics got their chemist to come to North America, temporarily, and improve the performance of their powders. The 2000MR and 4000MR are examples. Reloader 26, manufactured in Switzerland by Nitrochemie, is imported by Vista Outdoors, under the Alliant brand. From the Quickload data provided by IHFarmer07, note that the second powder on the list that you might actually get enough in the case, Swiss 70, is also a top performer but has a faster burn rate than R-26. When selecting a powder using quickload, you want to get enough in the case to reach the pressure you selected. 64K is likely the maximum and I might choose 63K or 62K in the program, for longer case life, but I reload and shoot a lot. Second, look to see that you burned all of the powder, or nearly all, in the barrel. Work up slowly, Quickload is a computer program, primers are not a variable you can choose, so expect that you reach unfavorable pressures before the program predicts. [/QUOTE]
