My "theory" is if I have 5" of wobble at 500 and the rifle is half inch. Thats 7.5
If you and another inch to the rifle that that turns it into 12.5 and as the distance increases what the rifle adds keep increasing.
While my ability to shoot stays the same.
Due to all the shots that land inside the cone and normal distribution, it washes out.
And actually it’s half the cone. So a .5 “MOA” rifle is 2.5” at 500, divided by two which adds 1.25” to your wobble zone for a cone size of 6.25”, or 1.25 MOA on target (if my math is correct). Using a 6.5 Cm with 147gr ELD-M at 2,700fps MV, at 5k DA, the hit rate for that in absolutely perfect conditions (that no one can call) is 99.9% on a 12” square target.
A 1moa rifle with the same exact conditions and wobble zone is a 7.5” cone for a 1.5 MOA total cone, and it’s hit rate is- 99.4%
No human on the planet can shoot, notice or observe the difference of .5% hit rate.
Now let’s look at a 1.5moa rifle and the same conditions- it becomes a 1.75 MOA cone, for a hit rate of 97.9%- no one can see the difference-
Now let’s look at realistic ability to call wind in “no wind” conditions. For most “trained” and “practiced” shooters, they can call wind to within 2mph in broken terrain and easy conductions, with a range error of around 2 yards using a LRF at 500y. That results in hit rates using the above rifle examples of-
.5 MOA gun, 5” of wobble is 96.6%
1 MOA rifle, plus 5” wobble equals a 1.5moa cone, with a hit rate of- 94.8%
A 1.5 MOA rifle, with a 5” wobble becomes a 1.75 MOA cone, which is 92.3% hit rate-
The amount of shooters in this country that can observe the difference of 4% hit rate in the field, in perfect to nearly perfect conditions, and killing enough animals to see it can probably be filled by the fingers on your hand. It’s a joke statistically. When put into real numbers that “practiced” shooters can do in field conditions as far as wind calling (+/-4 mph), precision (even prone of 2’ish MOA at minimum), range errors using a LRF (up to 5m average), etc… Once a rifle system mechanically is consistently putting 95+% of its rounds inside a 2 MOA cone, there is no observable benefit to be had by smaller groups for sub 500’ish yards. Once it mechanically is a 1.5 MOA system, out to 600+ yards there is no difference to better precision. And a real 1 MOA, or 1.25 MOA system (besides being uncommon), extends that to beyond where almost any bullet will perform correctly terminally. Real .5 MOA rifles are bench rest rifles- they are not field guns that people carry and people are delusional believing that their 8lb rifle is actually a .5 MOA rifle.
I also be its only money, and the only thing typically holding you back from an ok rifle to a precise shooter is money and some time to have it built. So why not.
Because as I wrote and showed above, there are about zero field rifles that are .5 MOA guns. There are very, very few that are 1 MOA rifles. 1.3-1.5 MOA rifles and systems can be had, whether custom or the better factory rifles. To go from 1.5 MOA real precision to .75 MOA is a stupid amount of time and effort that is totally wasted as it does not increase observable hit rates.
