Thanks for the reply. I never heard of using cornmeal, however, bringing the ball closer to the barrel makes sense.
I keep reading about the possibility of chain fires and I really have a hard time believing that with a properly fitted and seated round ball, that you could get fire in from that end to create a chain fire. I could see more easily how an improper fitting nipple or a nipple that falls off could possibly get a spark to ignite the cylinder, and that even seems a little far fetched as well.
Don't get me wrong, I'm not doubting that you or anyone else has had them, I'm just not sure that with a properly fitted and seated round ball that it would be physically possible. I too, get a small ring of lead when I seat a .451 round ball, so I feel that I'm getting a good seal.
If you were using round balls that were too small, I could see how sealing the end with grease of some kind would be beneficial in preventing a chain fire.
I'm not an expert and definitely lack the experience of most of you, so my observations are only based on my limited understanding and experience. It does seem to me that as tight as the lubricated wads I'm using seem to fit, that they would/should prevent a chain fire from occurring from the front side.
When I was shooting yesterday, the bore butter from adjoining cylinders would partially come out when fired, so I don't see how the addition of the grease in the end would prevent a chain fire either. I do think it helps with lubrication and keeping the barrel cleaner. The Crisco I used seemed to stay in the end of the cylinder better...it was thicker.
I also meant to comment on the nipples. On the 1851 Confederate, the OEM nipples works well with a #10 Remington cap. I didn't see any difference between the OEM Pietta's and the Slix Shot SS nipples.
On the 1858 New Army, the SS nipples do not hold the #10 caps very well. I installed a set of the Slix Shot nipples in each spare cylinder that I bought, so that I could compare them to the OEM Pietta's. The Slix SHot SS nipples worked much better than the Pietta SS's.
I will probably put both sets of Slix Shot's in the 1858, and put the OEM Pietta regular nipples back in the 1851 Colt. If I start to experience problems with the OEM regular Pietta nipples, then I'll order some more Slix Shots for the Colt as well. For now the ones that came in the 1851 hold and fire the Rem #10's just fine.
