Hello I'm new here and this is my first post so forgive me if this is a dumb question. What is the difference if a bolt is shot peened in a fixture or a rotating drum? Advantages/disadvantages etc. Thanks

Nobody has a answer to this?
Well... there are a lot of different standards for shot peening. They all do the same thing more or less. Those standards are SAE standards and are standard across all manufacturing. The .mil has a standard which is also an SAE standard as well.
As long as the process meets the specific standard there wouldn't be any difference. Ultimately the process just dimples the surface to reduce compressive stress.
To give an idea how "techie" the shot peen standards are this is the SAE version of the .mil standard.

...and yet people wonder at why the military is reticent to adopt an entire new whatever, lolQuote:

AMS 2430 bans the use of batch, tumble, drum peening UOS by the cognizant engineering organization i.e. Colt.
We shot peen thousands of bolts and extractors a year for this weapon in various calibers but primarily .223. Each part is individually shot peened meeting the requirements of AMS 2430.

I guess you need to trust a guy who goes under the username "shotpeen".
