I just read an interesting article on the Military/police version of the Rem 700 (military classification M-24 SWS (Sniper Weapon System) when I did a search for the specs.
When I got to the accuracy section this is what it said: (cut and paste)
"Accuracy: According to MIL-R-71126(AR), 3.15.7 Targeting and Accuracy, The rifle shall achieve the dispersion set forth below when fired from a Government approved machine rest. The average mean radius shall be less than or equal to the values stated below. The minimum rate of fire for conducting this test shall be three rounds per minute.[3]
Range / Average Mean Radius (AMR) — Mean Radius (MR) expresses the average distance of all the shots from the center of the shot group. AMR averages the MR of several shot groups.
The actual rifle requirements for accuracy were .35 MOA from a machine rest and according to Major John Mende (ret.) this accuracy had to be maintained to 10,000 rounds. He stated, "Interesting side note was there was a 10,000 round requirement for the barrel to maintain the original accuracy. In fact after some 10,000 round tests we discovered the accuracy improved. A few barrels were tested past 20,000 and accuracy never went below the original accuracy requirement."[8]
Maximum effective range is given as 800 meters (875 yd), but record shots have been made with the M24 at over 1,000 meters (1,094 yd). Meanwhile, the standard optical sight has a maximum elevation adjustment of 1,000 meters (1,094 yd)."
I know a lot of guys swap out their barrels after less than 10,000 rounds and some a lot less than that. This rifle system was adopted by the military in 1988 with many in use today in either .308 or .338 Lapula.
