[QUOTE="nemesis, post: 3561402, member: 12082"] That's a strong gun. You can explore the upper limits of the cartridge with that one. Now, for cowboy action shooting with the 1873 toggle link action, it has to be much milder. VihtaVuori N320 or N330 is good. For a 200 grain bullet, 8.0 grains N330 will take up the most room in the case on the low side. Some charges, like Win 231, are pretty small volume. Some powders are position sensitive and ignition can be sporadic, giving uneven results. Accurate #5 will take up the most volume for the low side of a 200 grain bullet: 10.4 grains for 908 fps. All the above is careful to keep max pressure under 14,000 psi which is the limit for the 1873 toggle link action. (Toggle link is fragile by comparison to the 94.) [IMG]https://www.gunsamerica.com/blog/wp-content/uploads/2016/09/Toggle-open1.jpg[/IMG] Apparently, that's also the limit for the Colt SAA. But Rugers and all model 94 levers have much more powerful load data, which, yours does. Titegroup for the 1873 w/200 grain bullet starts at 6.5 grains. All above data is for the 45 Colt. And one other consideration for the 1873 is the blowback. With the original 44-40 cartridge, the case mouth expands under pressure, creating a seal that keeps powder and debris from flowing back past the case mouth into the action. But the 45 Colt is straight walled and doesn't expand enough to stop blowback, especially when we're talking about loads for (more) fragile firearms. That's why dirty powders like Unique aren't too good. But powders like VihtaVuori N330 are much cleaner. So, there's always that. I know the info about the 1873 doesn't apply to yours, but I'm supposed to be picking up an 1873 in 45 Colt next week. And it's becoming quite an interesting project. [/QUOTE]
