BlackBuzzard Posted October 9, 2008 Share Posted October 9, 2008 I use my Ruger mark III for practice on steel plates. Its one year old and has seen about 18,000 rounds of Federal Bulk Pack through it. Lately, about one in every 15 rounds splits the case lengthwise and fails to eject. This has to be an ammo problem right? No way is my chamber suddenly out of dimension. Also, the firearm gets quite hot when in use since I run lots of mags all quickly loaded with speedloader. This can't be part of the problem could it? BB Link to comment Share on other sites More sharing options...
MichiganShootist Posted October 9, 2008 Share Posted October 9, 2008 (edited) Make very sure you don't have a huge lead build up. My Ruger once got so bad that I literally drove a tube shaped piece of lead out of the barrel with a cleaning brush.

taco101 Posted October 10, 2008 Share Posted October 10, 2008 Try liberaly coating the bore in Kroil. Let it sit for a bit, then follow it with a jag and VERY tight fitting patch. The Kroil gets under any lead that is built up and the tight patch pushes it out. I had to do that to my 22/45 at the 8000 round mark. Lots more lead/copper/? came out than I expected.

kevin c Posted October 11, 2008 Share Posted October 11, 2008 Did you try another brand to see if the problem continues? Link to comment Share on other sites More sharing options...
BlackBuzzard Posted October 11, 2008 Author Share Posted October 11, 2008 Did you try another brand to see if the problem continues? Will try winchster on Monday. I cleaned the Mark III real well and the chamber didnt seem to have more than normal leading or copper buildup. A .22 round will easily drop into chamber and fall back out when inverted. When the split cases are viewed from back, with the firing pin mark at 12oclock, most of the lengthwise splits occur at the 8oclock position. If it were totally ammo related I would expect this to be random. Thanks for the feedback. If I can find some Kroil I'll give it a try. BB Link to comment Share on other sites More sharing options...
BlackBuzzard Posted October 14, 2008 Author Share Posted October 14, 2008 Ok for those still following this saga of the split 22LR cases.............. Today I ran Winchster ammo with no split cases........though it sometimes likes to nose-dive into feedramp and stop, unlike Federal. In conclusion it must be a bad lot of Federal 550 count bulk ammo. Will Wal Mart allow me to switch unopened cartons out for different lot # of same brand? After some reading online, I think the case extrusion die (at the Federal factory) has a flaw in it that puts a scratch or line down the interior of the cases. This line thins the case enough to allow many cases to rupture in the pistol chamber. This is the best explanation I have found so far. BB Link to comment Share on other sites More sharing options...
pmd Posted October 14, 2008 Share Posted October 14, 2008 If Wally World does dot allow the switch (I think they have a no ammo return policy) you should contact Federal and tell them about your ammo issues - or try to contact a local or regional Federal sales rep. Good Luck. Link to comment Share on other sites More sharing options...
Flexmoney Posted October 14, 2008 Share Posted October 14, 2008 18,000 rounds? Sure sounds like leading in the barrel...increasing pressure. The build up might be shiney and hard to notice. If the Federal brass splits easier, that may just be an early warning indicator. Link to comment Share on other sites More sharing options...
BlackBuzzard Posted October 14, 2008 Author Share Posted October 14, 2008 18,000 rounds? Sure sounds like leading in the barrel...increasing pressure. The build up might be shiney and hard to notice. If the Federal brass splits easier, that may just be an early warning indicator. Yes it is shinny, but I do clean it every few thousand rounds.........have to given how filthy .22 can be. I Use a brush with either hoppes 9 or a decoppering cleaner. Federals are copper plated. Should I go back and furiously reclean the chamber and barrel with brush and alternating diff. gun cleaning solvents? Again......the Federals split like one in 15........winchesters all ok ( an all lead bullet) BB Link to comment Share on other sites More sharing options...
LPatterson Posted October 15, 2008 Share Posted October 15, 2008 The copper color on the Federal is not really a plating as much as it is a wash. Scratch it with a knife blade and you can see how thin it is. I think I would be contacting Ruger as they might like to see it. Link to comment Share on other sites More sharing options...
gm iprod Posted October 17, 2008 Share Posted October 17, 2008 I think I would be contacting Ruger as they might like to see it. Wise idea. I use lead solvent not copper solvent, it works better. Hoppes 9 is the best alrounder for this job, put in plenty and leave it for 15minutes. Bruch and repeat until the rag comes out totally clean. Not gray in colour. It can take some time with certain guns and ammo combinations. Link to comment Share on other sites More sharing options...
BlackBuzzard Posted October 24, 2008 Author Share Posted October 24, 2008 Ok...............verdict is IN on the split .22LR cases. Same ammo (Federal value pack 550 count from walmart), but different lot number runs almost flawlessly with zero split cases after 500 rounds in same pistiol. When I switch back to the suspect Federal 1AW603 lot number, its back to one out of fifteen cases splitting. Now I need to contact Federal about the four full remaining cartons of the bad lot still on my shelf. BB Link to comment Share on other sites More sharing options...

Para 16 Posted November 19, 2008 Share Posted November 19, 2008 (edited) BTW, try Federals 510 load and "Dicks Sporting Goods" carries the 714 load... GOOD stuff for not much money, its supposed to be the Gold Medal rejects. Shoots damn good in my 10/22!
