Hi all

I was wondering, when it comes to corrosive and non, what are the main differences..

I know non-corrosives have a higher chance of becoming duds over time, (at least i read that somewhere)
and that corrosives, although..corrosive, tend to be cheaper,

other than this, are there any differences?

do non-corrosives have higher pressure, and are therefore not good in older firearms?

or is the main reason people use corrosive ammo simply because it's somewhat cheaper..

thanks for any clarification

Replace somewhat with A LOT and that's my reason. :D
 
I don't think there is any difference between the two, apart from the fact that corrosive priming is better in extreme cold conditions and also apart from the fact remainig residue contains some traces of potassium chloride, a very hygroscopic salt that gathers humidity from ambiant air and helps corrosion take hold in your chamber and bore if left there for any amount of time.
The two kinds of ammo can be very accurate and effective.
Just try some good 8mm Mauser war surplus and you'll be surprized by the power and accuracy of these old rounds.
If living in a very dry climate, corrosion will not affect your firearm as fast as in a damp, humid weather.
Just remember: these salts are very soluble so flushing your bore and chamber with enough water before cleaning should take care of them unless some oil has been slopped over them before.
That's why very hot water with just a few drops of dishwashing liquid soap takes care of them.
The heat will only allow the barrel to dry very fast and you'll be able to begin your conventional cleaning routine faster.
Have fun!

There is really no difference in them. There has been speculation over the years that corrosive primers were more consistant. But this had more to do with the development of the NC primer and varying compounds. The reason corrosive ammo is cheaper is that they are used in surplus military ammo which is cheaper because it was sold as scrap by the militaries, not because it was corrosive. The higher pressure myth has to do with the facto that rounds like the 8mm mauser are loaded to the correct spec in Europe and underloaded in the US.
 
Not really. They are available on the International market but there is no demand in North America, so they are not imported. There are no real advantages to chlorate corrosive primers. What are you looking to reload?

Because it would be different and if I could track down original German type smokeless used in their 8mm Mauser I could reload a EXACT copy of the load they used for 8mm Mauser to feed my FN49. :dancingbanana:

well, I am not a chemist but if I remember correctly they do not contain a lead compound. Firing indoors could theoretically be less of a health concern :rolleyes:

I'm reaching here. Anyone?

I've got some Czech & Eqidorian stuff thats a punisher;)
 
British Army estimated the life of current noncorrosive primer at 100+ years. Have shot 1880s corrosive ammo. Many corrosive primers contain mercury which is a health hazard.

Not since before the war. Mercury was removed and potassium chlorate increased.
 
.303" cordite was loaded with a mercuric primer until c1960 in Britain because Lead Styphnate was incompatible with cordite.

The FN49's Belgian made and was never in German service.
 
Stevo,

I realize that. But I've been thinking it would be easyer to find information and try to copy the German Service round then the Egyptian one. :)
