If you are using the taper crimp in the seating die to remove the flare, then you are mildly taper crimping. So yes, always crimp your semiauto ammo ofr proper functioning. Leaving the flare or bell, even only 0.001" can cause feeding issues.
There have been reams written about the uslessness of the LFCD. A poor solution to just about any problem your ammo may have. If you need a LFCD to get your ammo to work, then you need a reloading class not a LFCD.
"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".
