It's tough to locate .303, .30-06 or 7.62x51 military ball ammo which will do better than 2 MOA. Back when the FN was used for competitive shooting the idea was to locate a particular lot of ball ammo which would shoot better and to then secure a quantity of this lot for competitive shooting. I think that it would have been pretty tough to locate and fence off a better than average lot of ammo for snipers in a combat theatre. Snipers only accounted for a very small fraction of ammo as most was used for MGs and rifleman on the line. Small arms ammo is issued by the truckload and lot number control for sniper use would be an expectation that would have been very hard to deliver on.
The .303 with it's longer 174gr bullet exhibited good ballistic performance at extended ranges as did the .30-06 M1 ball which used a 172gr bullet. M2 ball with a 152gr bullet was the most common .30-06 ammo used in WW2, although a lot of 168gr AP ammo was also put up in Garand en blocs. I remember buying a swack of this in en blocs from the old Super S Drug Store in Calgary back in the 1972/73 timeframe (how drug stores have changed). Because of it's better long range properties 168gr AP was used for competitive shooting by the US services post WW2 until match ammo with a 172gr boattail was re-introduced. And guess where Sierra got the idea of developing their benchmark 168gr Match bullet for competitive shooting.
For those who believe that every No4 Mk1 (T) was capable of gilt edge accuracy, Cdn Army E.M.E.I.s tell a different story. The required grouping standard for 5 shots with ball ammo was 3"x3", although many would do better. I recommend the book, With British Snipers To the Reich, by Capt. C Shore. This provides a wealth of information on various weapons, ammo and sniper tactics. Shore was very fond of the P14 Enfield and mentions getting consistently good accuracy with W.R.A. produced contract .303 ball ammo. Interestingly, this ammo was loaded with a ball powder which later morphed into the BLC2 that we are still shooting today. Shore opines that an EXCELLENT shot could put up consistent 3-4 MOA groups with ball ammo and iron sights @ 100 yds while a SUPERB shot was one who could produce consistent 2 MOA groups @ 100 yds with a scoped rifle. This tends to confirm that a man who was shooting a mechanically sound rifle with excellent shooting techniques was reaching the accuracy limitations of most wartime ball ammo.
Shore ran a sniper school for the British Army in NW Europe and makes a lot of practical observations based on his experiences. He stresses the proper use of fieldcraft for a successful sniper and notes that a good shot with a hunting background generally made a better sniper than did a "range lizard".
It's not necessarily the military ball ammunition that limits its accuracy if that makes sense which is about what you stated regarding the rifles that were being used to shoot the stuff.
The rifles they were being used in were not inherently accurate in general. They were rough, mass produced battle rifles.
Canadian C21 IVI 7.62 NATO Ball that's been made since the 60's is capable of very impressive accuracy out of a modern rifle designed for precision from the ground up ie thick barrel, floated from the receiver, precision trigger, very good modern optics, a bedded action etc People would be amazed at the prerequisite manufacturer (IVI) specs dictated by DND as far as maximum allowable dispersion of the cartridge at long distances for a basic ball cartridge. It's expected to be very consistent.
