That is not to say that you won't damage the gun by repeated firing of over-pressure loads.įor any long range shooting, one should obtain bullets with the highest Ballistic Coefficient (BC). The M14 is designed to withstand obscenely over-pressure loads without blowing up in your face. But, it doesn't reduce the chamber pressure. This reduces the force of the bolt coming back. Some shooters (usually military teams with access to unlimited replacement parts) install barrels with reduced-diameter gas ports on their 1000-yard rifles. It would be a shame to do that to that fine piece of equipment from Clint. The next symptom is a cracked receiver from the force of the bolt slamming against the back of the receiver. Attempts to push it much further will soon show up as blown primers. MatchKing has a better BC and can be driven almost as fast, reaching the target without going subsonic.ĭoes anyone have any info they can share concerning bullet selection and long range shooting with the M1A?įor years the "standard" match load for the M1A/M14 class of rifles has been what the military calls "M852." Normal velocity for M852 is 2600 to 2650 feet per second. I've heard the Berger 168 gr LBT has better performance than the Sierra 168 gr MatchKing but is it going to have the same trouble at 1000 yds? Or possibly the Sierra 175 gr MatchKing. Apparently the bullet starts to yaw as it goes subsonic which has a negative effect on accuracy. The bullet I'm using is the Sierra 168 hpbt MatchKing at 2800 fps muzzle velocity from a Fulton Armory Peerless grade M1A. The M1A does great at the 600 yd range but starts to get somewhat iffy at the 1000 yd range. Fulton Armory FAQ: The M1A at 1000 yards The M1A at 1000 yards by Gary M.
