It's generally conceded that the smaller calibers are more accurate....however I believe is solely because of their effect on a shooter....it's a lot easier to sit at the bench with a .223 than a .375 H&H!!! However, it should be noted that the .375 H&H is very capable of 1/2" groups!!!

In general, I'd not believe some calibers are more accurate than others.....Now for the 6PPC...if you was machined and crafted like this cartridge is, you'd be shooting superbly too...the difference is extremely small, yet enough to get a benchrest fella real excited.....maybe .025 at 100 yards. In standard vermint and hunting rifles extremely few can see a difference.....if in fact one really exists.

Velocity, power, ballistics has little or nothing to do with accuracy.

For a hunting rifle it's almost totally irrelevant.....

There are some that argue that short actions are stiffer and as a result are more accurate. In theory this makes sense.....but in fact it's just more talk. Ask them to prove it once!!!

Here's the bottom line: Unless you're a benchrest shooter used to shooting groups in the 1/ 8" range (100 Yards) there's no caliber more accurate than another and power, velocity is not a factor.
