Here's the winning scores shot in the NRA's 1000-yard Wimbledon Cup Match fired with any rifle having any sights from prone; typcally with scopes:

The history on what the course of fire was along with other match conditions is interesting.
1875 to late 1890's;
Target; 36" 5 ring (black aiming bullseye), 54" 4 ring, 72" square 3 square, 2' x 6' panel on each side scored 2 points. Black powder 45 caliber 500 grain bullets with a long telescope. Accuracy about 25 to 30 inches.
1896 to 1919;
.30-40 Krag with 220 grain bullets, then in 1903/4 M1903 Spfld with 150-gr. bullets. 20 to 25 inch accuracy.
1920 to 1934;
.30-06 round in M1903's, M1917 Enfields and from 1926 on the Winchester 54 was added. The M2 machine FMJBT machine gun bullet of 173 grains bucked the wind a lot better; the 2' panels on the targets was removed; now 6' wide instead of 10' so more could be on the firing lines. Scores moved up with the new "match" bullet. Winchester & Western along with Remington also made some heavy FMJBT 180's for competition. There were many unbreakable ties with perfect scores of 100, so a 20" V ring was put inside the 36" 5 ring and hits in it were used in ties to determine the score plus V count. Best lots of 30 caliber ammo would shoot about 20" at 1000 yards and that was the criteria for the V ring diameter. At 600 yards, that target's 20" 5 ring (black bullseye) had a 12" V ring in it for the same reason; the accuracy of .30-06 ammo at 600.
1935 to late 1950's:
A .300 H&H Magnum was used in 1935 to win the match with a M1917 action and Western factory ammo. More 300's showed up from then on, but scores with them were very close to what the .30-06 prouduced and sometimes less than. Sierra Bullets' 180 and 200 grain FMJBT match bullets had proved better than any commercial ones as well as the best lots of military M2 match bullets. Sierra hollow pointed them after their 168-gr hollow point did so well in international competion. And Fred Huntington's .30-.338 was outscoring the old .300 H&H round in the wind starting in the late '50's. Best accuracy was not much over 10 inches at 1000 with Sierra's. With good lots of jacket material, 10" accuracy was the norm. Extermally adjusted scopes were normal. Epoxy bedding receivers was beginning to be worthwhile. Wincheser's Model 70 came out with a heavy .300 H&H Mag barrel that was excellent. Their .30-06 actions were by far the favorite of all. Remingon 721's were tried, were few and far between. Proper full length sizing of fired cases were normal, but the belted ones didn't shoot quite as accurate as new ones.
1960's to 1974;
.30-.338 Win Mag's were common and the .300 Win Mag gave them a run for the money as did the .308 Norma Mag. The .30-06 droped out of favor in the early 70's as it was out scored by the .308 Winchester by folks choosing not to use magnums. Sierra's 30 caliber 190's came out and along with their 200-gr. HPMK's, best accuracy with them tested in positions now used in F-class competition was in the 7 inch range. Epoxy bedding had become popular and helped receivers stay repeatable in position relative to the wood stocks. In 1970, a Navy man used a 7mm Rem Mag with a super accurate batch of Sierra's 168-gr. match bullets and won the match with a 100-20V +12V record score. He told me the next year that rifle probably shot under 7 inches with ease based on his calls versus bullet impact. But subsequent lots of that new 28 caliber heavy match bullet rarely equalled what that prototype lot did until 15 years years later. That score was trumped by a .30-.338 by a Marine Corps warrant officer in 1972 with the then record score of 100-20V +23V with new unprepped cases; good lots of them were excellent. 43 consecutive shots from a 30 caliber magnum inside 20 inches at 1000 yards. Full length sizing was typical for fired cases, but belted ones were sized again with a body die squeezing down the body diameter all the way to the belt getting rid of the ridge left by the chamber headspacing shoulder.
1974 - mid 1990's;
The century old target finally got changed to a decimal one; too many unbreakable ties were shot with better bullets from epoxy bedded barreled actions. A 10" X ring inside a 20" 10 ring inside a 30" 9 ring inside a 44" 8 ring which was the aiming bullseye; much easier to see with metallic sights. The 54" 7 ring was inside the 72" square target area worth 6 points. Internally adjusted scopes were producing better scores than the externally adjusted ones. Best accuracy with the 30 caliber magnums for 20+ shot groups were in the 6 inch range. The 7mm magnums finally got decent bullets from Sierra but the 6.5mm ones were catching up fast. After a 6.5x.284 started taking home all the marbles, belted cases started loosing popularity. Best accuracy with all of them was still in the 6" range. The lighter recoil of the 6.5 made it easier to shoot more accurate.
1995 to Date;
Nothing much changed; bullets, barrels, and all that stuff's been decent. Tube guns became popular as they have no bedding issues and easy to make shoot as good as anything. Best accuracy is as good as 1000-yard benchrest guns when tests are fair and proper; all fired shots under 6 inches with 10% of the groups being very small and 10% very large. 1% of the groups are at extremes both tiny and huge. All the rest are in between.
