N320 starting load

Looking for some advice. I am switching powders from WST to N320. I have an Atlas Nemesis with 5.0” kkm bull barrel in .40. I am relatively new to reloading and have never worked up my own load before. My friend had given me his WST load when I started reloading. After doing some research, it seems the average major load is between 4.6gr -4.9gr with a 180 grain bullet loaded to OAL of 1.18. I want to continue to use 180gr coated bullets and I want to keep the OAL at 1.18. My question is, what should my starting load be? I saw in the Vihtavuori website they said to start with 3.6gr, but that was at an OAL of 1.126.

Any help would be appreciated.

Edit: misread some figures in the first post. Disregard the numbers.

Those Vihtavuori starting load are usually pretty conservative. Make just a few with 3.6gr and chrono them. I'm sure you will be well below Major PF. If you are looking at the same table as I am, you'll be near 900fps. If so, see what happens with 3.8gr.

 

Almost there? Add 0.1gr. Ways to go? Add 0.2gr.

Yep. I’d start at 4.5gr of N320 and work up from there.

My load in my pistol is 4.7.

Huh? At 1.180” OAL with 180gr coated .40s&w, you’re about a full grain low.
