I'm working on loads for my CW9 with W231 and the Lee 105 gr SWC bullet. The 3.5 gr. loads of W231 with this bullet that is so accurate in my CZ Compact won't function in the Kahr. The CW9 has a very stout recoil spring. I get a lot of stovepipes, FTE & failures to pick up the next round as the slide isn't going back far enough. A load of 3.7 grains of W231 will function in this pistol but the brass is piled by my right foot.
I've looked for loading data on this bullet/powder combo and can't find the max load. I do have a max load of 5.5 grains of W231 with a 100 gr. Speer FMJ.
The most powder I've tried so far is 4.1 grains of W231. This functions great but I'm looking for a more accurate load.
Any comments on how high I can go. My gut feeling is, not too much over 5 grains. I'm sure I'm like most of you: the most accurate load is generally not the hottest and I'm trying to develop a "not hot" practice load.
Thanks, Cloudpeak
