Thanks for info Bridgport28A1. Great read. Isn't it awesome that so many of the Small Arms Review articles are now online. While no specs are given in Frank's article, the weighing of his bolts seems to indicate the Military Specifications need to be 1 pound 11.5 ounces.
Quote from Frank Iannamico Article
"I used a recently calibrated postal style scale calibrated in ounces. Surprisingly, every M1 and M1A1 bolt checked weighed almost exactly the same at 1 pound 11.5 ounces. The only variation was that two of the M1 and M1A1 “bright” bolts were 0.25-ounce lighter than the others."
I have weighed the 2 bolts I own. One is an M1 parkerized bolt which weights in exactly at 1lb, 11.5 ounces. The other bolt is an M1A1 bolt with fixed firing pin in a blued finish. It weighs in at 1lb, 12.3 ounces. This bolt is an interesting example because it does not have either a Savage nor an AOC stamp on the rear flat. My best guess is that it is a West Hurley bolt?
I'm wondering if this heavier unmarked bolt could damage my M1 if fired extensively in the firearm?
The other question I have is regarding the cuts in the M1 parkerized bolt. Is this what you are calling "Sand" or "Mud" cuts? Or do you think the milling was done to get the bolt to the correct weight of 1lb, 11.5 oz? See attached pics.
Would appreciate others weighing their M1 bolts and adding to the data.
