Ok well I'll try and answer these questions (I admit ammo is not my norm)
The canvas "bags" say this on them:
CAL. 30 BALL M2
5 RD Clips
HXP 3010-73
The bullets themselves are stamped "HXP 73"
They are exactly 3 3/8" Long with tip
If I JUST measure the "shell" it is 2.5" Long
So 30-06
-----------------------------
The American Eagle ammo is definitely 30-06:
Markings: F C
30-06 SPRG
"Shell" is also 2.5"
Tip brings it to 3 1/4" overall
-----------------------------
Remington
30-06 Sringfield 220 grain core-Lokt Soft Point
"Shell" is also 2.5"
Tip brings it to 3 1/4" overall
Markings: RP
30-06 SPRG
