.318 was used in Commision rifles, many were be-barreled and have an S stamped on the bore. There are also Sporters that are .318, but those are not common and are quite rare. I, or IR not J is the .318, IS or IRS is .323. The Germans used fancy letters and silly Americans just got it wrong.

I have shot thousands of rounds of 49 dated Turk thru my various 8mm mg's and except for an occasional dud no problems at all. The 47 dated Turk was the worst for split necks right out of the bandoleers. However since the Turk ammo is light ball in every Mauser or semi that has sights calibrated for heavy ball that I shot the sights had to be set at 500 yards to hit point of aim @ 100 yards IIRC.

I found quite the opposite. I found 1949 Turk to be about 3" high at 100 yards, that is through 3 different Mausers. The trajectory of light ball and heavy ball only becomes an issue after 400 yards. The Germans used Heavy ball for sniper rifles. The standard German round in WW2 was 147gr.

I have 6000 rounds of German 39-41 dated ammo in the original 300 round boxes and it is all heavy ball. You are correct it is marked with a big red MG.

It is actually IS with German scriptive "I" that looks like a J. "I" is for Infanterie (infantry) and "S" is for the upgraded-from-ball Spitzgescho▀ (Spitzer) bullet. The latter was a real .32.

They are both .32 or 8mm rounds. Just as 7.62x51 and 7.62x54r are both .30 caliber. What sometimes gets lost is how the "round" was measured. Was it the old style lands, or the new fangles grooves?
7.92 which is what would be on Military ammo is actually .3118", so the original designation was lands, New 8x57 uses a .323 bullet, that is 8.20mm. 7.5 is .308, 7.62 is .311. Can I confuse you more??
