Re: Your most accurate centerfire rifle.....
center fire... hmmmm... would have to vote my M1A, the gun is 063,xxx serial number but was rebarreled and worked over good by the military armorers at camp perry many moons ago. the barrel/bolt are 7 million and something serial number.
But I hope to beat it with a new bolt gun, long overdue for one. Thinking either .280 rem or go for a .300 mag, probably .300 WSM or the RUM. Still need a M24 setup also though... hmmm.. so many guns, so little green in the wallet...
doesn't matter what bullet/powder combo you throw down the pipe, the M1A holds point of impact on all of them and it's stupid accurate, especially considering it's a gas gun. Even with iron sights, I can usually out-perform everything else I own. Some of my old 03-A3's are very accurate though also, even the 2 groove barreled one.
the .17 HMR I have (marlin) and my .22 target rifles are more accurate but rimfire so don't count.
