NO! I am not saying that at all! I am saying that there are no particular cartridge designs that are inherently INACCURATE! What I mean by this is that it is possible for ANY cartridge to produce an acceptable level of accuracy if the combination of gun, load, and sighting equipment is right! Granted, it is EASIER to develop exceptionally accurate loads for some cartridges than for others. Many " over-capacity" (whatever that is!!) cartridges are much fussier about what you stuff in them, for sure!

I am well aware that short, fat powder columns, like those in the PPC cartridges, the wildcats based on the .284 Winchester, etc., generally produce more efficient, consistent burning of the powder charge, and hence, less variation in muzzle velocities. I am also aware that loads which produce the least velocity variation are thought to be the most accurate, but very often are not! I have personally chronographed loads in some calibers which gave more variation in shot-to-shot velocity and produced smaller groups than some more consitent loads! This means, for example, that the Lyman Handbook' s " POTENTIALLY MOST ACCURATE LOAD" often does not turn out that way in any given rifle.
