BLueDot is a decebt powder in th e9mm, but only for high end loads IMO. It will be a compressed load @ even midrange vel levels, there just isn't much case room to work with. To check your OAL, load a dummy round & drop it into your remvoed bbl. It should fall in & out easily. Your powder charge is fine, load up 10 & go try em.
"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".
