The records speak for themselves the rest is just nonsensical trash talk.
Okay, so which "two" rifles do you have? No trash talk here I'm just looking for someone to quantify the statement that seems to be used so easily.
You asked if some cartridges are more inherently accurate, did you not?
That may be the "rule" but there are always guys trying to win with the newest greatest thing or we would have never had a 6br in competition. We would have never had the 300WSM winning because the 300 WM used to win in the wind. I guarantee people in benchrest fclass are trying new things. I have even seen some trying Rich's cartridges.One thing about looking at records and what BR guys use is once one guy wins with one cartridge then every body else switches to that. So it isn't necessarily "the best", just the one that won...same with barrels and actions...a guy with wins with a Bartlien then the following comps you'll see more and more Bartliens, then someone will win with a Brux, well you get the picture...short and fat is always more accurate until a long skinny cartridge beats it.
We answered that. Case capacity, fill ratio, and burn rate. After than in the distance are the things Rich mentioned. Steeper shoulder angles and less body taper. On average the shorter fatter case with a steeper shoulder angle will be more efficient which leads to accuracy. When it is calm the most important part of accuracy is vertical. When the wind blows horizontal obviously has to be paid more attention to. In both cases vertical matters and large overbore cartridges just will not maintain the tight vertical of the br or WSM cases. There are numerous cartridges that will hold better wind but you need both components to be accurate.No, I asked what made them more "inherently accurate"?
The CM based cartridges and 308 based cartridges were used as examples because they have similar case capacities in the same calibers.

I know, and the 6.5 creedmoor kills T rexs from mars.The PPC will spank a BR and a WSM...and the 338/378 is still the 1000 yard king...
