I too agree with the concise terms of a precision rifle and have to support Ian's remarks about relating to a particular task.
A BPCR open sight Sharps lobbing 550gr of lead at a silhouette 500m away might have amazing precision AND accuracy at only 2MOA.
A SR BR rig of today can be described as microscopic. 1/4 min is a well worn rifle.
A "working" rifle has to stop an enemy no matter what the ambient conditions subject the rifle to - cold bore 1 shot group is EVERYTHING. That rifle may only send the next 4 shots at MOA accuracy but it is more then up to the job desired.
An F Open rig has to hold 1/2 min V bull even when the barrel is sizzling hot and typically fouled by many many rds.
There are so many disciplines in shooting with varying goals and requirements. precision/accuracy in one context may be laughable in another but ALL disciplines have something to teach.
As for cost being a determinant, slippery slope with only ego and bruised bank accounts to show. There is an enormous range of costs that provide the same performance especially down to the 1/4 min level.
Since this is shootng, holes in paper is what matter. If a $300 just so happens to shoot at the same level as a $5000 custom, why not?
As long as the reported accuracy is repeatable as described not one hero group, have at it.
In drag racing, it's all about the time slips.

20 EXTREME Long Range Varmint Wildcat
So what a bout a long range/varmint rig with after market barrel, stock, trigger, and quality long range optics chambered in some wildcat like varminters are famous for? If this type of rifle is never meant for a competition is it now considered not to be precision?
Edit: KDX beat me to the varmint rig.[/QUO

I think that I have a wildcat that fits the bill as a Precision Rifle. I call it the 20 EXTREME as it was designed to propel 32 grain bullets from 3800 to 4200fps and 40 grain bullets from 3450 to 3650 fps with 20.0 - 22 grains of Hodgdon Extreme Powders. The 222 Rem case necked to 20 caliber, with 30 degree shoulder and trimmed to 1.575" was just the right size.
I chose a CZ 527 V action with a Kevlar stock and fitted it with a PacNor, SS, Super Match, 24" barrel with 1-11' twist. I fitted it with a Leupold VXIII, 6.5-24x40 LR scope with the Varmint Hunter Reticle as it exactly fits the trajectory of the 32 and 40 grain bullets. It actually shoots the same trajectory as the 22-250 Rem with Factory 55 HP bullets.
In working up loads I used two different barrels, six different cases, four different powders and nine different bullets (all as they came from the box). I shot in all conditions from 0 - 28 degrees Celsius with winds from calm - gusting to 30 km/hr. All groups were shot from the bench with bipod and rear bag. Fastest velocity was 4300+fps with Barnes 26 gr. Varmint Grenade with 20.7 gr H4198 and slowest load was 3414fps with Sierra 39 BK and 21.2 grains H 4895.
Only Remington 7 1/2 primers were used.
I shot a total of 151 targets with mostly 5 shot groups at ranges from 50 to 100 yards and one 3 shot group at300 yards (0.218MOA). The largest 100 yard group was 1.3" and the smallest was 0.015". Nine groups were over 1" due to 24 fliers likely due to wind, out of round brass or shooter error. In all I shot 780 rounds, while working up loads and the aggregate average for 151 targets was 0.68".
BEST GROUPS TO DATE

Laverne
i would say it would be people with rifles capable of shooting Sub MOA, that gets rid of most big game hunters, people with mini 14's. it keeps the varmint hunters, which i would consider precision shooting (very small target further distance)
in general people who aren't happy with a Dear sized kill zone more a chipmunk or squirrel kill zone.

lclund1946,
Nice rig and shooting. Here is a pic of my Wildcat and a couple targets from initial load development. It is 22-243 Middlestead Savage 10fp, 26" McGowen 1-8", 6.5-20X50 Mark 4. I was using H1000 pushing 77GR SMK's. The chrony stopped working at 48 GR's (was getting too dark out I think) but they were just over 3500 FPS. I still have some tuning to do but it looks promising.

Extremely long range varmint rifle
Looks like you have an EXTREMELY LONG RANGE VARMINT rifle. Think you might have it nailed at 48.8. I would try 5 at 48.7,48.8 and 48.9. The picture of the targets I shot during load development with H4198 show the difference 0.1 grains can sometimes make. The 20.9 grain target was shot at about 5 degrees Celsius and the rest were shot at about 20 degrees Celsius. The 20.6 grain load was the sweet spot.
