What is the latest thinking in right or wrong when shooting with oil in the barrel. I am sure we have all forgotten to clean the oil out of the barrel before heading to the range. Old school thoughts were you and all those around you were in mortal danger from exploding gunparts.
Surely the oil just gets pushed out with a slight increase in pressure. Oil viscosity etc have also changed from the exstra heavy duty engine oil we used way back when?
I have on more then one occasion done this. The question is, is it even worth cleaning the oil out of the barrel or should/could one just let rip and use the first shot to clean the barrel?

worst part is the oil burns just like the gun powder and leaves varnishes and unwanted residue in the barrel, some guys in the US shoot ars wet, which means  they give a squirt into the chamber to make sure the ar doesnt seize the case, the first couple of shots look more like black powder, but no bad effects. I don't think is possible to get all the oil out, unless you use a final rinse of brake cleaner or alcohol.

For what its worth, I shot my .270 at the range a few years ago after it had been cleaned and oiled up for summer storage. I knew there was still some oil in the barrel. The bullet didn't even hit the target at 100 yards. Second shot was dead on. After that experience, I now take the time to run a patch with solvent on it and clean the oil out before shooting.

A few guys have recommended to me to run a dry patch through a couple times when I get to the camp to wipe off any excess oil before I start hunting. That seems to work fine, no errant first shots.

I'm sure this is over thinking something simple but I'm a little hesitant to run a solvent patch through because from a corrosion standpoint I didn't want a completely dry barrel for 3 or 4 days at time out in the weather. The micro-film of oil left after dry patching didn't seem to hurt accuracy and may give a little corrosion protection when the gun gets rained on.

There's some pretty good evidence that the wrong oil, in the wrong quantity can cause crazing in the barrel.  WD40 ( really a penetrant ) will pretty much cause hydraulic fracturing if you shoot with the stuff in the bore.
 
I'd think that to do the really memorable stuff though you would need to pack the barrel with gear lube.

Ok, this makes sense, the oil penetrating the barrel cracks etc.

Now this is a line I could borrow!!!!
