As a general rule, given equal bearing surfaces, or body, pointed bullets are more accurate than flatnosed, but not a lot more accurate, and they don't kill much better than a darning needle. Also, accuracy is determined more by precision of the mold, how well the bullet fits the gun of interest and bullet design. Bullet design in the bearing area is very very important to accuracy, which is way the LBT flatnose bullets have cut a pretty big swath since I developed them. Also, I bend over backwards to train every customer on how to make bullets from my molds give optimum performance. No other mold maker seems to care as long as the customer doesn't complain, and very few do if they can get the bullets into their gun. You see, if bullets slip into the gun easily, like jacketed bullets do, the mold customer just thinks bad performance is his ignorance about cast, so says nothing to the mold maker about bad performance. I started LBT because I couldn't make cast bullets from any of the manufactures work, and, except for some of them adding a few bullets that look similar to LBT designs, nothing has changed in their offerings in the 28 years since LBT has existed.
Maybe what I'm trying to say here is, if you buy a flatnose bullet mold but it isn't an exact copy of an LBT design, or if the bullets aren't precision, or if they don't fit your gun with precision, then flatnose won't be more accurate than pointed, or equal.
