Wow, what a question. The custom bullet maker could have the edge when it comes to keeping the tolarances of a match bullet to a minimum, and I have found Bergers to be very accurate in fast twist barrels. I still haven't seen any of the aluminum tipped bullets from Wildcat, but I hope to soon. When you consider the hundreds of millions of bullets manufactured by the big makers, match bullet accuracy is very good across the board. At one time I thought that a Hornady 168 gr International Match would out shoot the 168 gr Sierra MK, but the advantage did not last. Nosler J-4's I thought were quite good, and a little cheaper to shoot that the MK's. I have only shot a small number of Lapuas, perhaps a thousand or so, but from what I've seen they are very good. as said above it depends more on what bullet your rifle likes.
In a hunting bullet, terminal performance trumps accuracy, and the hunter should always consider what job he expects his bullet to accomplish. Most of us cannot shoot under 2 MOA in the field at any rate, so a bullet that is capable of quarter MOA is of little advantage. Seeing a bullet totally fail will underscore this point.
It happened to me when I loaded Speer 130 gr hollowpoints in my .30-06. These bullets shot close to half MOA, but the effect on the one seal I shot with these things was abysmal. It took several shots to put the poor thing away as it dragged itself around on the sea ice, and finally a neck shot finished it. An autopsy showed that none of the bullets penetrated into the body, and the bullets exploded on bone leaving only flecks of jacket material in a fist sized hole. I thought these bullets would be super deadly, because most shots on seals are head shots, but this guy was facing away from me on the first shot, and although he would raise his head from time to time, I didn't have a good shot, so elected for a body shot. At the shot he went down his hole, but quickly came back up on the ice. As it happened his back end was paralysed, and he could only pull himself around on his front flippers. The subsequent shots, 4 of them, were broadside, but he was moving, and the neck shot was more luck than good planning.
No one wants to intentionally inflict this level of distress on an animal, and I will never use those bullets again on anything but light framed animals. So there you have it. Base you bullet choice on the weight and body structure of the game you are hunting, and take into account that the bullet will have to work regardless of the angle of the shot.
