LEAD AND BURNED POWDER—I have a .22 caliber Model 1000 Winchester, and it handles the short cartridges all right, but will not extract the longs and long rifle cartridges, and I must use the blade of a knife to get them out. There appears to be a ring of rust in the chamber, a little over half way from the breech end to the rifling. Can this be removed by perchloride of tin, 12 1/2 drs., tartaric acid, 1 dr., distilled water, 1 pint; or can you give some other method of removing the rust? Thinking it was lead, I tried mercury, also rag and oil, but without results. This rifle is chambered for the .22 long rifle cartridges; will it prolong the life of the barrel If I use only the long rifle cartridges in it?
I think the ring in the chamber is not rust, but lead and burned powder, caused by using the .22 short cartridges in a rifle chambered for the .22 long rifle. The bullet from the short cartridge must jump straight forward through a smooth bore for some distance, before it strikes the rifling, and when it strikes this part a portion of the lead is shaved off and deposited in the forward end of the chamber. Each shot adds a little more, until it reaches back to the bullet of the short cartridge, and this deposit gets harder and harder, and is very difficult to remove. Although you have used mercury, I think you did not use it in the right way. Try corking the breech (don’t push the cork forward too far or you will cover the leaded portion) and allow the mercury to stand in the gun overnight, then pour it out and wipe clean. I think you would have no trouble in removing it with Marble’s Nitro Solvent Oil and a brass wire brush. When you have removed the obstruction you can avoid a similar trouble in the f u- tore by using only the .22 long rifle or the .22 Stevens-Pope cartridges.
