.60 cal

Two of my eight .60 cal’s in my collection API and Incendiary

Sqeeeeeeeze the trigger. Re the first photo. :-)

HEY I croped didn’t I LOL


  • @ stevef: One of the rounds [from the top photo] still has the black ink marks visible on the side. Can you post here those markings??? Thanks, Liviu 03/04/09 P.S. What type of round is the one dated 1947???

Both US 60 cal rounds. FA 47 is an API round with the marking on the side. FA * * 51 is Incendiary which also has markings on the case but barely visable

I could not get all the text in the picture. It says

LOT NO. 24

  • @ stevef: I have a fired .60" / 15.2X114 brass shell case [also headstamped “FA” over “47” and badly dented at the shoulder area] which has no side markings left. I was expecting more side markings such as: type of projectile, type of propellant, etc. Liviu 03/05/09 P.S. I should mention that my fired .60" / 15.2X114 brass shell case is crinkled [with longitudinal markings] showing the gun which fired it had a fluted chamber in order to aid extraction.

Dummy round

Three of the 1948 H/S differnt Cannulers

  • @ stevef: I only have two .60" / 15.2X114 brass shell cases, both fired. One is headstamped “FA” over “47”. The other is headstamped “SL” over “44” with a 5-corner “star” barely visible at 3 o’clock position. Normally “SL” stands for “St. Louis Ordnance Plant” [from St. Louis / Missouri] but from what I know that particular “star” shows that the round was made at “Frankford Arsenal” [from Phiaelphia / PA] using tools removed from St. Louis Ordnance Plant. => It looks like the 0.6-inch / 15.2X114 round was developed in US from the German MG151 for the “T1E1” anti-tank rifle and the “T17” aircraft gun [both weapons were never used in combat]. After 1950 the 0.6-inch round was finally modified to become the well-known 20X102 potent round. => QUESTION: Which is the earliest and latest date marked on a 0.6-inch / 15.2X114 headstamp??? Liviu 03/05/09

Man! Look at those close-ups! Steve, you’re a quick study. Congrats.

Slick Rick

LOve that tulip!!!




The Oldest date I have is FA 45, newest FA 51. I would like to assemble a H/S check list. If everyone could list your headstamps for the .60, that would be great!



There’s a lot more to the Cal 60 cartridges than you would think. HWS II devotes 30 pages to it. Shows different cases, a lot of headstamps, and a plethora of bullets too.



WOW! I would have never thought. I knew there were a lot more than I have, but not that many!


Here’s my contribution - sorry about the poor quality. The previous owner coated them with polyurethan, which didn’t help the pictures.

Headstamps are in the same order as the side view of the cartridges:
CAL. 60 LOT 7663 W.S.M.CO. 42, S L 44, F A 45

F A 47, F A * 48 *, F A * 50 *, F A * 51 * (the stars have 5 points)

Thanks Guy!!!

Incidently, the cartridge in the picture headstamped CAL. 60 LOT 7663 W.S.M.CO. 42 is one of the developmental cases with more taper - the shoulder measures 1.003" rather than the 1.045" - 1.050" of the later examples. Also, the last three have electric primers.


I noticed that most of the electric primed ones have the heavy neck crimp. However my percussion primed FA * * 48 round also has the heavy neck crimp.


Are you looking for headstamps alone, or do you also want projectile variations within a given headstamp?

I have a ball round with a projectile/crimp similar to the one on the right in Guy’s photo (electric primer) with no headstamp.

If you’re looking at projectile variations too, I have an inert-loaded ball round (electric primer), headstamp F A * 48 *:

Guy, can’t you remove the polyurethane? I use a product called “NitroMors” to remove lacquer. This is a clear gel paint stripper product that you paint on with a brush then wipe off later, taking the lacquer with it. I have yet to see any lacquer that this stuff can’t remove. There is probably a similar product available in the USA.

What is the average price for a .60 Cal round in the USA? There are a few in the UK but they seem to be about

My records show I paid $42 for my 60cal ball ( F A 50 ) round at SLICS in 2007.
IIRC the asking price was $50, but was was reduced as part of a multi-cartridge deal
