Hi,
I did a fair bit of testing with N140 and SMK 174. Nothing too an*l but wanted to get a nice shooting accurate load.
I ended up at 41 grains which I believed is a “go to” load and within Vihts load data.
It also works with the PPU 174 bullet so seems stable.
I haven’t obsessed about matching it to the rear sight markings although it doesn’t seem too far off.
