So, took the JRC out for a little spinCycled my old duty ammo, and some FMJ ball I just had lying around, and bought a couple of boxes of CCI Blazer from the shooting range.The JRC did NOT like the Blazer aluminum caseThe extractor actually BENT and BROKE the rim of the shell casings, causing double feeds (Failure to chamber followed by failure to fire, followed by failure to extract, followed by feeding into a loaded chamber during tap-rack-bang drill)Has anyone ELSE seen or heard of this? This is the first time I've seen aluminum shell casings with a solid, extractor-shaped DENT in the rim, deep enough that the rim itself is actually torn at each end of the dent.Wish I'd taken a pictureIt's one of those quot;oh shtquot; moments.So.is it the gun, or the ammo?
Well , the foil didnt melt, aluminum melts around 1800 FYOu have cheese goo holding it to the bottomSo see if the oven has a self cleaning feature and run the cycleI like to be at home when you do this as it gets very hotThen you should be able to just carefully scrape it off with a hard plastic scraper once it coolsAlternately, you may be able to scrap it with the oven warm, say 400, but if its burnt, you probably need to run the self clean cycle
The foil has indeed totally melted, like mercury would - on my Frigidaire Professional Series oven! And I promise everyone, it will not come offHave been soaking it for days, and what is left (looks like broken mirrors in the bottom of my oven) will not budgeNo scraping this offAny chemists out there?
Aluminum Foil Melted In Oven
I TOO Have a brand new oven ended up with two sheets of aluminum foil melted to bottom floor of ovenI read the booklet that came with oven tried all their ideas with no luckI also ran oven through the self cleaning procedure with no luckeven scraping it with a hard plastic edge like a spatula won't get it looseI'm now soaking the area with liquid fabric softener but doesn't seem like that helps eitherI just moved into this home that I rent definitely if Landlord sees how I messed up this brand new oven it'll cost me big timeHELP!!!
I don't have a JRC, however I have had something like this happen on a different platformIn that case what was happening was that as the slide (I had it happen on a pistol) cycled and picked up a new round, the round below that in the mag was getting dragged forward in the magThen when the slide would cycle to pick that one up the rim would be in front of the extractor instead of behind it and flush to the breech faceHowever the recoil spring was strong enough to ram the slide home causing the extractor to be forced over the rim of the case and chewing it upIn that case it mostly had to do with the ammo, the cases were sticky enough that rounds didn't slide smoothly when feeding, and were loaded light enough that the slide short cycled just a little bitI ended up just using better ammo and the problem went awayAs I said though, it was not on a JRC so take it with a grain of saltThinkingblade Edit - as a note and as I'm sure you know Lime, aluminum is much less lubricious than brass and even with the CCI stuff I've also seen that the casings are not polished to the same degree as brass cases.
