goldkey, I have a update on your bolt, from your previous tread,
http://www.gunsnet.net/forums/showthread.php?threadid=59361
after talking to my buddy...who is still in the Army, he says it sounds like you may have a old M2 practice training bolt, that was used to fire the M862 plastic practice cartridge for shooting in indoor ranges. the active army got rid of them when they went to the M261 .22 conversion bolt, thereby using off the shelf .22 ammo, which is cheaper then them making these plastic practice cartridge.
he indicated that it is not a good idea to fire regular rounds with it, as it may cause the bolt to have a catastrophic failure, that may cause you bodily harm, because of the chamber pressure is very high, then the loads in the plastic training rounds, and the bolt is of weak metal…also the head spacing for the bolt although not really needed for the plastic ammo, bcause of the low pressure…..will not be the proper for regular ammo.
I suggest you replace it with a real bolt, before something happens you don't need or want, on your next shooting session. Just make sure you have the real bolt head spaced to your rifle…..don't buy one and put it in, and figure it will be good to go.
