Dry lube for extraction

[sdh1911]

I'm wondering if I put dry lube on steel case ammo, would the pressure be effected? In the 1920's Pederson was experimenting with a wax like lube on the bullets in a proto type semi auto. Was this to increase back pressure for operation? Back to the original item, if I used a very light coating of a dry lube, would this help with extraction? The only reason I asked is I still have 2 cases of steel case stuff, Thanks and merry Christmas-SDH

I honestly don't know if it would be problematic or not. I suspect alot of it would depend on the lube and the particle size. The danger is that it might act like grit on a fine level and cause the case to stick enough to create too much pressure.

In "German 7,9 mm Military Ammunition" Kent, it states that after July 1944 all steel case ammo was waxed to improve extraction in the MG42.

Of course when the MG42 was developped, most ammo was brass cased and extracted just fine.

In Germany, steel cases were an expedient in WW1 and WW2 as the copper in brass became scarce.

The Luger really hated the steel case ammo and users tried wherever possible to secure brass cased ammo. The P38, on the optehr hand, ate it up and was very often issued the steel cased ammo.

The K98k with it's HUGE extractor claw didn't much care either way

MG42 is gas operated and digest steel case ammo w/o any problems. Other German autoweapons were recoil operated and needed casefriction reducing measures to ensure extraction.

MG42 isn't gas operated, apart from the muzzle booster.

You have a gas operated muzzle booster, a rod ( the barrel) that transfers the impulse and an rollerlock action, that unlocks on this gas operated impulse. What more do you need. Of course it is gas operated. BTW, Rheinmetall sold the patends a few years ago and so the MG3 will vanish from German Army in due course.

[tiriaq]

Most gas operated firearms have a gas cylinder and piston. If a muzzle booster makes a moving barrel firearm gas operated, then there are a lot of recoil operated MGs that should be reclassified as gas operated.

[cannonball]

Its indeed a question of definition. On an extended firing with a MG3 we forgot to cleen the booster ventopenings, which were clogged with burned oil debris. The result was the same as with any other gasoperated ventclogged gun. Lots of mulfunctions.
