I know this is an older thread but I’m hoping to gather some more info from guys who use this powder for 40 s&w coated bullets, specifically in CZs. I’m currently loading 4.5gr of TG at 1.334 OAL making PF at 170ish for my TSO. I have one pound each of SP and N320 on the way, and I also have a bunch of HS6 that I bought for loading 9major.
curious to know what your load was using the n320, and also if you had and reliability issues loading at 1.145 OAL?
appreciate any advice that any of you have!
