I went the range yesterday and tried the CCI Mini Mags and the bullets jammed...failure to eject. When I went to the CCI standard velocity with the lead tips....worked like a charm like it did before....I was very happy with it againWe need to slow down a bit...
OK, you are going to shoot CCI Mini Mags. Those are perfect for testing.
As far as an adequately clean chamber goes you should be able to drop a new, clean round into the chamber. Gravity will cause it to drop with a plunk. If it doesn't then we need to look at other things.
Likewise if you tilt the pistol muzzle up the round will slide out of the chamber. It might be necessary to shake the pistol a bit.
If all of the above works then you are ready to go shooting. Forget about manual extraction for the present. Just load and shoot. Keep a firm grip on the pistol and the spent cases should fly out while the slide chambers the next round. If the spent cases won't extract or eject when firing...then we have to dig deeper.
There are slight differences in the shape of rims one brand of ammo to the next. The extractor might work on some and on others not when manually cycling the slide. We will tackle that next. First, remember, when firing the extractor plays no part in extracting a spent round. Burning gasses that propel the projectile out the muzzle of the barrel also blow the spent case out of the chamber with enough energy to cycle the slide and cock the hammer and bounce the case off the ejector and out of the pistol.
Check if rounds drop into the chamber freely and then go shooting. Firm grip. Then report results. One thing at a time. 1917
