There is no smg ammo thats a myth. Its all smg and its all handgun, there are no special loadings for smgs. Different powders from different countries have different burn rates which make them feel different when you fire them. They all chrono about the same. And for the split necks I would not worry too much, I ran a whole spam can of some Yugo or Polish (can't remember which) where every round had a split neck before or after firing. No effect on the gun.
actually there is differenceThere is no smg ammo thats a myth. Its all smg and its all handgun, there are no special loadings for smgs.
incorrect.I don't know whether or not there is 7.62x25mm loaded hotter for smg's but I can give you this advice if you're really worried about shooting smg ammo in a pistol... One way to tell if the ammo was intended for pistol or smg is to look at the packaging. If it comes in brown paper packets of 16 rounds tied up with twine, it was intended for pistols (two mags of 8 rounds each) or packed in boxes of 70 or 72 rounds it was intended for smgs.
I'm not saying the ammo in boxes is any hotter than the stuff in paper packets, it's just that the Com Bloc countries packaged ammo certain ways for easier distribution to their troops.
So they made two identical dimentioned rounds with two SPECIFIC loads and DID NOT bother to label them.....or place a warning on the box...or publish a Soldiers manual telling of the use of each???? Come on, the PPSh gets a higer velocity because of the LONGER barrel. Why, tell me WHY you want a "hotter load" for a PPSH41 when you have been using that round in your handgun for YEARS and have warehouses FULL of ammo already to go.actually there is difference
7.62x25 made for the pistols shoots 1100-1400fps (big variance)
the carbines (PPSH41) need 1550+ to cycle properly, which is why there are some rounds which have been chrony'd @ 1600-1700fps.
Hearsay is that ammo is typically not imported into the US, because it will damage the weaker Tokarov pistols (safety issue?)....
(Think of it like shooting 9mm IMI black tipped ammo out of a Hi-Point)
So 840rd cans of 5.56mm ammo are "Marine fire team Specific"? HELL YES That is a concidence! What does a 11 man Army Squad draw for ammo? How about a SEAL team? You don't understand the amount of ammo packed in that can just happen to be the number of rounds that fit in a can designed DECADES before the 5,56mm round was adopted? What foresight!I've never heard of anyone outside of special forces carrying 9 pistol magazines into combat, especially when the handgun was only issued with 2.
Hmm... 70rds... PPS used 35rd magazines... 70 divided by 35 equals 2
72rds... PPSh used 35rd magazines or a 71rd drum... a 71rd box just doesn't make sense, nor is it practical. 9 rows of 8, or 8 rows of 9
.30-06, 20rd boxes... BAR uses 20rd magazines, M1903 uses 5rd stripper clips... 20 divided by 5 equals 4. US M1923 Cartridge belt has 10 pockets, each pocket holds 2 M1903 stripper clips or one 8rd M1 Garand clip. 2 stripper clips x 5rds each x 10 pockets = 100rds divided by 20rds in a box = 5 boxes issued to each M1903 or M1917 armed soldier. 8rd M1 Garand clip x 10 pockets = 80rds divided by 20rds in a box = 4 boxes issued to each M1 Garand armed soldier
shall I go on to do the math for 6 pocket US bandoliers?
I never said the ammo was loaded for SMG, I'm just saying it was packaged so that each soldier could quickly grab enough boxes, or packets of ammo to reload quickly.
Many guys I served with would never load more than 28rds in their M16 mags, because it might wear the spring out faster, or because they thought it was faster to do a tactical reload with less rounds in the mag. But that didn't stop the DoD from packaging M885 on 10rd stripper clips, 3 stripper clips to a mag x 7 mags to each marine = 21 stripper clips. 210rds divided by 840rds in an ammo can = ammo for 4 marines, is it a coincidence that a "fire team" consists of 4 marines?
reasons don't run well ppsh...weight displuming inertia by drilling out for firing pin, weight loss. geomatry, longer barrel changes things too as Lyman suggestedSo they made two identical dimentioned rounds with two SPECIFIC loads and DID NOT bother to label them.....or place a warning on the box...or publish a Soldiers manual telling of the use of each????

SMGs are designed to use PISTOL AMMO! It is just that simple. And guys get off that "size of the box means" stuff. Does USGI 30-06 packed in 20rd boxes have some special load in there for BAR use only???
