Wehn I loaded for the 380, W231 was my choice for 88gr-102gr bullets, but many powders work. OAL as always, bullet & gun specific.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
