I can probably help. I have developed 2 loads for a 340.

Each individual rifle is different, and will likely have a preference to a different load.

I typically start with a large lot of brass, all prepped, and then review for typical good powders for the cartridge. Initially, i test at 50yds to see what looks promising, and then final tests at 100/200yds. Choose a standard weight projectile, standardized on primers, and have a feel for what is "good enough " accuracy with a good velocity. Your most accurate will likely not be at max V and pressure.

I review my targets using mean radius, and not the extremes. Enjoy the experiment.

250 gr. Nosler partition . My 340 loved that load

I've got two GAP rifles and was planning on reloading, but I found factory loads that are easily 1/2 MOA.
