I realized today that the last IDPA match of the year in my state is in less than two weeks and I was thinking about doing it. It will be my first.
I am accustomed to loading 185 gr coated LSWCs over 4.6 grains of Bullseye for general range shooting with a 5" 1911. I need to figure out what my load would be to make the 165 power factor.
I realize 185gr is not the best way to make 165 power factor, but it's what I have (a LOT of).
Looking at the Lyman guide, I see that the min load of 3.5 gr yields 678 fps, and the max recommended load of 5.6 gr yields 975 fps. In order to make a PF of 165 I need a velocity of at least 892 fps. So somewhere just south of 5.6 should be good, but how far south?
I do not have access to a chrono. Does anybody have load data for a 185 gr LSWC and Bullseye that will reliably make 165?
Before anyone chews me out for not searching, I've been looking all over the place, but almost universally if someone asks about 185gr, the thread immediately becomes a thread about how 230gr is preferable.
Thanks
