Warning about putting oil on loaded ammo

Some full auto firearms require oil to be sprayed on the ammunition before using it. The Italian Breda MG is one.

It is usually dangerous to oil cartridge cases before shooting them. There is a great deal of expansion of the ctg case to the chamber walls and if the ammo is oiled, it will cause excessive bolt thrust to the rear.

The reason I am mentioning this is , a fellow brought a Savage 99 in .243 Win to me because the wood was shattered and he needed the stock replaced. As a matter of form I checked the headspace. The chamber would eat the field gauge with almost 1/8" to spare. He then told me they were having problems with extraction. They oiled the ammo and the problems stopped. What it did was cause excessive bolt thrust and it actually increased the headspace to the point that the ctg cases separated. The high pressure gas escaped into the action and shattered the buttstock. All they would have had to do was clean the chamber. A nice 99 was ruined this way.

I have my neighbor reloading for me and sometimes I have
a 'sticky' fired case. Wondering if the case lube he's using has
anything to do with this. I 'finger feel' them before loading but can't detect anything on them. A break open Encore
I never had this happen til I started shooting reloads. Not really a problem but I don't want it to escalate into one either. Got some brake cleaner, maybe spray em down and clean em, would that be Ok ya think ?
yea I hear ya, my only gripe about the guy is He wants to start with the maximum charge for everything. Finally got him to load some down for me and groups are improving. My first experience
reloading, so I get led (by the nose) around so to speak.
He's been reloading for nearly 40 years of his 50 +.

Just short on patience I perceive
I've been front stuffin mzlder's since there was a season for them in MS and been from one extreme (max load) to the other (great accuracy but ain't gonna clean kill crap). After much thought, reloading metallic crtg was preceded by front stuffers applying their knowledge of reloading for hunting.
