Well guys I guess experience is a good teacher. Just blew my MG42 bolt head in half with some turkish ammo, now I read about how that ammo is too hot for the gun, DUH ! My gun is a CRA MFG and I think the bolt was correct one marked AR , maybe original but there was no serial numbers on it. So I am looking for a complete or just the bolt head marked AR. It had a phosphate finish to it so I would like to get one to replace it that is exactly the same, anybody got one like that ? I have lots of other MG42 and mg34 parts to trade for it or would buy outright. Thanks for looking
Ok it was NOT a original bolt to the gun, CRA is maget and AR is mauser, either one would due for me.

You didn't ask for advice, but I'm going to jump in anyway.
You shouldn't be shooting a 70 year old bolt. Use an MG3 bolt instead. Old steel that's been under stress of any type can crystalize and shatter as yours did. The ammo may have contributed to it, but it could have just as easily happened anyway. 70 year old steel, made under wartime conditions with bombing and sabotage going on, and perhaps improper heat treatment and steel/nickel/chrome shortages, is not going to be the best choice for use when it's not necessary.
MG3 (modern) bolts are available from the usual parts dealers for reasonable money. Glad you didn't have it shatter and blow the gun.
Save some grief and shoot with an MG3 bolt (or bolt head for a semi). Save the antiques for show and tell.
