Agreed, you really need to try them all unfortunately. I've tried 3n38, hs-6, Silhouette, aa7, SWMP, SW autopistol, still not settled on a powder
For me I don't think 3n38 is all that it's cracked up to be, especially for the price.
I think Hs6 has the softest recoil for me, but the dirtiest. (Dot gets gummed up quickly)
SWMP and aa7 are a close 2nd, but like Chicago, I got the leftover "cornmeal" unburnt powder
Sil and Autopistol aren't terrible, kinda like them, different.
Cfe is horrible, lol
But that's my opinion, could mean something completely different for everyone else.
But I thought n350 was a faster powder, compared to sportpistol/cleanshot/titgroup, those wouldn't work your comp very well
