Not that many M1a's on the firing line anymore.
Except along with 7.62 Garands and AR10s, they've have won all the service rifle long range championships at the Nationals for the last several years. Scores fired with them are higher than rifles shooting 5.56 rounds. The US Army was able to get the AR10 added as a service rifle 'cause they didn't have any decent shooting M14NM's around to compete with.
Oh, forgot to mention....all with uncrimped bullets in their ammo
