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

 

[Doug Bowser]

The case lube may be getting pressed out of the pores in the brass.

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 ?

 

[Doug Bowser]

A small amount of case lube should not be a problem, These people were heavily oiling the cases.

If the rounds chamber in the gun fine and are sticky (as in slightly difficult to remove) only after firing, you may want to look for high pressure signs on the reloads, ie cratered and flattened primers ect.

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.

 

[ftsibley]

scary. Reloading can be a lot of fun if done right. Sounds like your neighbor may be an accident waiting to happen.

He's been reloading for nearly 40 years of his 50 +.

Just short on patience I perceive

I have been loading for 30+ years and still do not have desire or NEED to load anything to the max. Best performance and accuracy rarely occurs at the max load -- usually, it can be found around the mid to 2/3 load ...

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.

I sprays an 8 shot 22 revolver down with WD-40 several years ago before loading it and putting it in storage.

A few months later I got it out to shoot a snake.

I got:

I saw that on another forum. Never tried it but they advise to use the non-clorinated kind.

Lol. Yeah 22 ammo ain't wd40 proof.

Oiling cartridges

That's very true about oiling cartridges, it's a bad practice and the results can be catastrophic to both the weapon and the operator. A lot of oils and lubricants have the uncanny ability to creep into very small places such as the gap between the primer and primer pocket or around the bullet and case neck. It's doesn't take much oil to render a cartridge and/or primer a useless dud. Save the oils and lubricants for the weapons mechanical parts, not the ammo. Keeping your chambers and bores lubricated for protection when being stored is OK. Cartridges should always be clean and dry.....NO oil.
Good shooting!

What I was trying to say was the oil on ammo will cause excessive rearward thrust to the bolt face of a HP rifle . This can stretch the action as it did on the Savage Model 99 I worked on. The only way to fix the rifle would be, replace the barrel with a short chambered barrel and ream to head space the rifle. I was not talking about heavy loads or oil in the priming of the ammunition.

I am with Captain on most of the rifles I have reloaded for the sweet spot is arround mid range. I have had a few that shot their best at min. I can't imagine someone putting that much oil into the bore Doug that woud be just as bad as having some kind of foreign material in the chamber. ASKING FOR TROUBLE.
