If this ammo shoots well for you as is, i.e., accuracy, point of impact, your ability to control the gun and recoil, and quickly get back on target, you need go no further. Hitting your target consistently is far more important than bullet design, shooting through jello, water jugs, etc.

You already have a good weight bullet. Keep things simple and don't obsess over the "what ifs" that some people seem to thrive on.
