I thought I'd present an observation regarding what I see as Cognitive Bias in the Shooting Community
A cognitive bias is a systematic error in thinking that affects the decisions and judgments that people make.
I see this all the time... recently in guys challenging me on my 223 load development but I see it in so many other ways.
A friend (very experienced long range shooter) was recently telling me that he found a certain primer to be more accurate than another... He was testing groups on target at 100 yards to make this determination.... the problem with that is that the primer does not cause accuracy... it causes ignition, which affects speed... so measuring bullet dispersion at 100 yards does not confirm how consistent the velocity was. He should have been measuring how consistent the velocity was if he was evaluating primers.
There are lots of examples of this.... What's better for hunting moose... 308 or 30-06?
This is actually a loaded question.... Yes the 30-06 is more powerful at the muzzle, but the real answer depends on the specific bullet and distance to the moose. Use a low BC round nose bullet in one vs a high BC VLD bullet in the other and the results can change very quickly.
Here's another example... what's better a 243 or 6 creed or 6XC? It's really not a cartridge discussion at all... its really about the bullets being offered that most manufacturers are stuffing into the case and rifle makers are chambering for and selecting twist rates for
Back to the 223.... 223 has mostly been offered with 55 grain bullets... but fairly recently guys have been running faster twist barrels and heavier bullets, but the 223 is categorically no good for this or that. Deer hunting for example... Lots of guys will bump chests over using the 223 for deer hunting because its just no good for that.... but if you consider that more objectively... it comes back to the specific configuration.... guys will say its ok to hunt deer with 80 grain bullets with a 6 dasher but not ok with 80s from a 223.
Cheapness is also a factor... manufacturers make 223s for guys who want to use bulk milsurp 55 grain ammo... not 80 SMKs. So they don't get good accuracy with the light bullets from a fast twist... so again the 223 is no good for deer hunting right?
And magazine length is a factor... you just cant run 80 SMKs out long from most 223 magazines... but that is not a problem with the 223... its a problem with the typical 223 rifle configuration.
And then the PRS guys... they don't even say 223 any more... they say 223 trainer rifle... its automatically a trainer rifle. That's Cognitive Bias.
Guys so often attribute goodness to one thing or badness to some other thing when its not the thing... its the typical configuration of the thing, but that does not mean the same bad thing in a different configuration doesn't perform very well.
Take for example the new 308 Hornady 176 grain A Tip... G1 BC .564... That's right up there with most 6mms. That bullet is a game changer that has the ability to change pre conceived notions about how competitive a 308 can be in PRS.
Same with the new A Tip 90 grain bullet for 223... That bullet may well change the game for 223s... so its not the 223 at all... its the choice of available bullets with a high enough BC in combination with rifles configured for it.
When I look at the new bullets coming out, the BC gap is closing to the point that almost any caliber will have a bullet that compares to the best of any other caliber. The case and throat length just decides how fast you will be able to push it.
Any thoughts?
