that curiosity should serve you well in all this, not wanting to mitigate problems before understanding them.
some bullet types are indeed less "finicky" (as are some cartridges, powders, barrels, etc...). No experience with hammers (or most monos) but can indeed attest that flat base bullets are much less sensitive to jump than boat tails and are often more "easily accurate" within 3-400 yards as well.
hexagonal boron nitride treatment of bullets and the bore has also, in my recent and limited experience, made loads a lot less finicky regarding jump and less prone to pressure spiking when loading close to or on the lands.
